Spark's Apache Maven-based build includes a convenience script, 'build/mvn', that downloads and runs a zinc server to speed up compilation. It has been included in release branches since 1.3.x, up to and including master. This server will accept connections from external hosts by default. A specially-crafted request to the zinc server could cause it to reveal information in files readable to the developer account running the build. Note that this issue does not affect end users of Spark, only developers building Spark from source code.

Apache Wicket before 1.5.12, 6.x before 6.17.0, and 7.x before 7.0.0-M3 might allow remote attackers to obtain sensitive information via vectors involving identifiers for storing page markup for temporary user sessions.

A vulnerability in Batik of Apache XML Graphics allows an attacker to run Java code from untrusted SVG via JavaScript. This issue affects Apache XML Graphics prior to 1.16. Users are recommended to upgrade to version 1.16.

In Apache Hadoop versions 3.0.0-alpha2 to 3.0.0, 2.9.0 to 2.9.2, 2.8.0 to 2.8.5, any users can access some servlets without authentication when Kerberos authentication is enabled and SPNEGO through HTTP is not enabled.

Server-Side Request Forgery (SSRF) vulnerability in Batik of Apache XML Graphics allows an attacker to access files using a Jar url. This issue affects Apache XML Graphics Batik 1.14.

In Apache Airflow 2.3.0 through 2.3.4, part of a url was unnecessarily formatted, allowing for possible information extraction.

Arbitrary file reading vulnerability in Apache Software Foundation Apache OFBiz when using the Solr plugin. This is a  pre-authentication attack. This issue affects Apache OFBiz: before 18.12.07.

Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.

The Apache Airflow FTP provider's `FTPSHook.get_conn()` created an `ftplib.FTP_TLS` connection but never called `prot_p()`, so although the control channel was TLS-protected the data channel was transmitted in cleartext. Any deployment using `FTPSHook` or `FTPSFileTransmitOperator` to move files over FTPS exposed file contents and credentials-in-transit to a network attacker able to observe the data connection. Upgrade apache-airflow-providers-ftp to `3.15.1` or later, which issues `PROT P` to encrypt the data channel.

Exposure of Sensitive Information to an Unauthorized Actor in Apache ServiceComb Service-Center.This issue affects Apache ServiceComb Service-Center before 2.1.0 (include). Users are recommended to upgrade to version 2.2.0, which fixes the issue.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Lucene.Net (Lucene.Net.Replicator library). This issue affects Apache Lucene.Net.Replicator: from 4.8.0-beta00005 through 4.8.0-beta00017. Users are recommended to upgrade to version 4.8.0-beta00018, which fixes the issue.

Missing Origin Validation in WebSockets vulnerability in Apache Zeppelin. The attacker could access the Zeppelin server from another origin without any restriction, and get internal information about paragraphs.  This issue affects Apache Zeppelin: from 0.11.1 before 0.12.0. Users are recommended to upgrade to version 0.12.0, which fixes the issue.

Out-of-bounds Read vulnerability in Apache NimBLE. Missing proper validation of HCI Number Of Completed Packets could lead to out-of-bound access when parsing HCI event and invalid read from HCI transport memory. This issue requires broken or bogus Bluetooth controller and thus severity is considered low. This issue affects Apache NimBLE: through 1.7.0. Users are recommended to upgrade to version 1.8.0, which fixes the issue.

Insufficient escaping of user-supplied data in mod_ssl in Apache HTTP Server 2.4.63 and earlier allows an untrusted SSL/TLS client to insert escape characters into log files in some configurations. In a logging configuration where CustomLog is used with "%{varname}x" or "%{varname}c" to log variables provided by mod_ssl such as SSL_TLS_SNI, no escaping is performed by either mod_log_config or mod_ssl and unsanitized data provided by the client may appear in log files.

Exposure of Sensitive Information to an Unauthorized Actor, Insecure Storage of Sensitive Information vulnerability in Maven Archetype Plugin. This issue affects Maven Archetype Plugin: from 3.2.1 before 3.3.0. Users are recommended to upgrade to version 3.3.0, which fixes the issue. Archetype integration testing creates a file called ./target/classes/archetype-it/archetype-settings.xml This file contains all the content from the users ~/.m2/settings.xml file, which often contains information they do not want to publish. We expect that on many developer machines, this also contains credentials. When the user runs mvn verify again (without a mvn clean), this file becomes part of the final artifact. If a developer were to publish this into Maven Central or any other remote repository (whether as a release or a snapshot) their credentials would be published without them knowing.

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache HertzBeat. This issue affects Apache HertzBeat: before 1.6.1. Users are recommended to upgrade to version 1.6.1, which fixes the issue.

Apache Airflow versions before 2.10.3 contain a vulnerability that could expose sensitive configuration variables in task logs. This vulnerability allows DAG authors to unintentionally or intentionally log sensitive configuration variables. Unauthorized users could access these logs, potentially exposing critical data that could be exploited to compromise the security of the Airflow deployment. In version 2.10.3, secrets are now masked in task logs to prevent sensitive configuration variables from being exposed in the logging output. Users should upgrade to Airflow 2.10.3 or the latest version to eliminate this vulnerability. If you suspect that DAG authors could have logged the secret values to the logs and that your logs are not additionally protected, it is also recommended that you update those secrets.

Direct Request ('Forced Browsing') vulnerability in Apache OFBiz. This issue affects Apache OFBiz: before 18.12.16. Users are recommended to upgrade to version 18.12.16, which fixes the issue.

Server-Side Request Forgery (SSRF) in Apache HTTP Server on Windows allows to potentially leak NTLM hashes to a malicious server via  mod_rewrite or apache expressions that pass unvalidated request input. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.63. Note:  The Apache HTTP Server Project will be setting a higher bar for accepting vulnerability reports regarding SSRF via UNC paths. The server offers limited protection against administrators directing the server to open UNC paths. Windows servers should limit the hosts they will connect over via SMB based on the nature of NTLM authentication.

The attacker can use the raft server protocol in an unauthenticated way. The attacker can see the server's resources, including directories and files. This issue affects Apache Zeppelin: from 0.10.1 up to 0.12.0. Users are recommended to upgrade to version 0.12.0, which fixes the issue by removing the Cluster Interpreter.

SSRF in Apache HTTP Server on Windows with mod_rewrite in server/vhost context, allows to potentially leak NTML hashes to a malicious server via SSRF and malicious requests. Users are recommended to upgrade to version 2.4.62 which fixes this issue. 

Exposure of temporary credentials in logs in Apache Arrow Rust Object Store (`object_store` crate), version 0.10.1 and earlier on all platforms using AWS WebIdentityTokens.  On certain error conditions, the logs may contain the OIDC token passed to AssumeRoleWithWebIdentity https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html . This allows someone with access to the logs to impersonate that identity, including performing their own calls to AssumeRoleWithWebIdentity, until the OIDC token expires. Typically OIDC tokens are valid for up to an hour, although this will vary depending on the issuer. Users are recommended to use a different AWS authentication mechanism, disable logging or upgrade to version 0.10.2, which fixes this issue. Details: When using AWS WebIdentityTokens with the object_store crate, in the event of a failure and automatic retry, the underlying reqwest error, including the full URL with the credentials, potentially in the parameters, is written to the logs.  Thanks to Paul Hatcherian for reporting this vulnerability

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Pinot. This issue affects Apache Pinot: from 0.1 before 1.0.0. Users are recommended to upgrade to version 1.0.0 and configure RBAC, which fixes the issue. Details:  When using a request to path “/appconfigs” to the controller, it can lead to the disclosure of sensitive information such as system information (e.g. arch, os version), environment information (e.g. maxHeapSize) and Pinot configurations (e.g. zookeeper path). This issue was addressed by the Role-based Access Control https://docs.pinot.apache.org/operators/tutorials/authentication/basic-auth-access-control , so that /appConfigs` and all other APIs can be access controlled. Only authorized users have access to it. Note the user needs to add the admin role accordingly to the RBAC guide to control access to this endpoint, and in the future version of Pinot, a default admin role is planned to be added.

In Apache Linkis <= 1.5.0, a Random string security vulnerability in Spark EngineConn, random string generated by the Token when starting Py4j uses the Commons Lang's RandomStringUtils. Users are recommended to upgrade to version 1.6.0, which fixes this issue.

SSRF in Apache HTTP Server on Windows allows to potentially leak NTLM hashes to a malicious server via SSRF and malicious requests or content Users are recommended to upgrade to version 2.4.60 which fixes this issue.  Note: Existing configurations that access UNC paths will have to configure new directive "UNCList" to allow access during request processing.

In Apache Kylin version 2.0.0 to 4.0.3, there is a Server Config web interface that displays the content of file 'kylin.properties', that may contain serverside credentials. When the kylin service runs over HTTP (or other plain text protocol), it is possible for network sniffers to hijack the HTTP payload and get access to the content of kylin.properties and potentially the containing credentials. To avoid this threat, users are recommended to  * Always turn on HTTPS so that network payload is encrypted. * Avoid putting credentials in kylin.properties, or at least not in plain text. * Use network firewalls to protect the serverside such that it is not accessible to external attackers. * Upgrade to version Apache Kylin 4.0.4, which filters out the sensitive content that goes to the Server Config web interface.

Deserialization of Untrusted Data vulnerability in Apache InLong.This issue affects Apache InLong: from 1.7.0 through 1.9.0, the attackers can make a arbitrary file read attack using mysql driver. Users are advised to upgrade to Apache InLong's 1.10.0 or cherry-pick [1] to solve it. [1]  https://github.com/apache/inlong/pull/9331

Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer.

An LDAP injection vulnerability in the LDAP Certificate repository of the XKMS server in Apache CXF may allow an attacker to retrieve arbitrary certificates from the repository.  Users are recommended to upgrade to versions 4.2.1, 4.1.6 or 3.6.11, which fix this issue.

In APache APISIX before 3.13.1, the jwt-auth plugin has a security issue that leaks the user's secret key because the error message returned from the dependency lua-resty-jwt contains sensitive information.

Arbitrary File Read Vulnerability in Apache Dolphinscheduler. This issue affects Apache DolphinScheduler: before 3.2.1. We recommend users to upgrade Apache DolphinScheduler to version 3.2.1, which fixes the issue.

Multiple components in Apache NiFi 0.0.1 to 1.16.0 do not restrict XML External Entity references in the default configuration. The Standard Content Viewer service attempts to resolve XML External Entity references when viewing formatted XML files. The following Processors attempt to resolve XML External Entity references when configured with default property values: - EvaluateXPath - EvaluateXQuery - ValidateXml Apache NiFi flow configurations that include these Processors are vulnerable to malicious XML documents that contain Document Type Declarations with XML External Entity references. The resolution disables Document Type Declarations in the default configuration for these Processors, and disallows XML External Entity resolution in standard services.

Improper Handling of Case Sensitivity vulnerability in LockOutRealm in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Older unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.22, 10.1.55 or 9.0.118 which fix the issue.

Incorrect Permission Assignment for Critical Resource, Improper Control of Dynamically-Managed Code Resources vulnerability in Apache Solr. This issue affects Apache Solr: from 8.10.0 through 8.11.2, from 9.0.0 before 9.3.0. The Schema Designer was introduced to allow users to more easily configure and test new Schemas and configSets. However, when the feature was created, the "trust" (authentication) of these configSets was not considered. External library loading is only available to configSets that are "trusted" (created by authenticated users), thus non-authenticated users are unable to perform Remote Code Execution. Since the Schema Designer loaded configSets without taking their "trust" into account, configSets that were created by unauthenticated users were allowed to load external libraries when used in the Schema Designer. Users are recommended to upgrade to version 9.3.0, which fixes the issue.

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Wicket. This issue affects Apache Wicket: from 8.0.0 through 8.17.0, from 9.0.0 through 9.22.0, from 10.0.0 through 10.8.0. Users are recommended to upgrade to version 10.9.0, which fixes the issue.

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Solr.This issue affects Apache Solr: from 6.0.0 through 8.11.2, from 9.0.0 before 9.4.1. Solr Streaming Expressions allows users to extract data from other Solr Clouds, using a "zkHost" parameter. When original SolrCloud is setup to use ZooKeeper credentials and ACLs, they will be sent to whatever "zkHost" the user provides. An attacker could setup a server to mock ZooKeeper, that accepts ZooKeeper requests with credentials and ACLs and extracts the sensitive information, then send a streaming expression using the mock server's address in "zkHost". Streaming Expressions are exposed via the "/streaming" handler, with "read" permissions. Users are recommended to upgrade to version 8.11.3 or 9.4.1, which fix the issue. From these versions on, only zkHost values that have the same server address (regardless of chroot), will use the given ZooKeeper credentials and ACLs when connecting.

XML External Entity (XXE) via Unsanitized Dictionary Parsing in Apache OpenNLP DictionaryEntryPersistor Versions Affected: before 2.5.9, before 3.0.0-M3 Description: The DictionaryEntryPersistor class initializes a static SAXParserFactory at class-load time without enabling FEATURE_SECURE_PROCESSING or disabling DTD processing. When create(InputStream, EntryInserter) is invoked, the only feature set on the XMLReader is namespace support — external entity resolution and DOCTYPE declarations remain fully enabled. An attacker who can supply a crafted dictionary file (e.g., a stop-word list or domain dictionary) containing a malicious DOCTYPE declaration can trigger local file disclosure via file:// entity references or server-side request forgery via http:// entity references during SAX parsing, before the application processes a single dictionary entry. This is inconsistent with the project's own XmlUtil.createSaxParser() helper, which correctly sets FEATURE_SECURE_PROCESSING and disallow-doctype-decl and is used by all other XML parsing paths in the codebase. The public Dictionary(InputStream) constructor delegates directly to this method and is the documented API for loading user-supplied dictionaries, making untrusted input a realistic scenario. Mitigation: 2.x users should upgrade to 2.5.9. 3.x users should upgrade to 3.0.0-M3. Users who cannot upgrade immediately should ensure that all dictionary files are sourced from trusted origins and should consider wrapping the Dictionary(InputStream) constructor with input validation that rejects any XML containing a DOCTYPE declaration before it reaches the parser.

When using tasks to read config files, there is a risk of database password disclosure. We recommend you upgrade to version 2.0.6 or higher.

Arbitrary file properties reading vulnerability in Apache Software Foundation Apache OFBiz when user operates an uri call without authorizations. The same uri can be operated to realize a SSRF attack also without authorizations. Users are recommended to upgrade to version 18.12.11, which fixes this issue.

Incorrect Authorization, Improper Access Control vulnerability in Apache IoTDB. Authorization bypass in /rest/v2/fastLastQuery exposes last-value data to unauthorized authenticated users. This issue affects Apache IoTDB: from 1.3.5 before 1.3.8, from 2.0.5 before 2.0.10. Users are recommended to upgrade to version 2.0.10, which fixes the issue.

Hertzbeat is an open source, real-time monitoring system. Hertzbeat 1.6.0 and earlier declares a /api/monitor/{monitorId}/metric/{metricFull} endpoint to download job metrics. In the process, it executes a SQL query with user-controlled data, allowing for SQL injection.

In Apache Traffic Control Traffic Ops prior to 6.1.0 or 5.1.6, an unprivileged user who can reach Traffic Ops over HTTPS can send a specially-crafted POST request to /user/login/oauth to scan a port of a server that Traffic Ops can reach.

On Apache ShenYu versions 2.4.0 and 2.4.1, and endpoint existed that disclosed the passwords of all users. Users are recommended to upgrade to version 2.4.2 or later.

Apache Doris, prior to 1.0.0, used a hardcoded key and IV to initialize the cipher used for ldap password, which may lead to information disclosure.

Insufficiently Protected Credentials vulnerability in Apache Solr. This issue affects Apache Solr: from 6.0.0 through 8.11.2, from 9.0.0 before 9.3.0. One of the two endpoints that publishes the Solr process' Java system properties, /admin/info/properties, was only setup to hide system properties that had "password" contained in the name. There are a number of sensitive system properties, such as "basicauth" and "aws.secretKey" do not contain "password", thus their values were published via the "/admin/info/properties" endpoint. This endpoint populates the list of System Properties on the home screen of the Solr Admin page, making the exposed credentials visible in the UI. This /admin/info/properties endpoint is protected under the "config-read" permission. Therefore, Solr Clouds with Authorization enabled will only be vulnerable through logged-in users that have the "config-read" permission. Users are recommended to upgrade to version 9.3.0 or 8.11.3, which fixes the issue. A single option now controls hiding Java system property for all endpoints, "-Dsolr.hiddenSysProps". By default all known sensitive properties are hidden (including "-Dbasicauth"), as well as any property with a name containing "secret" or "password". Users who cannot upgrade can also use the following Java system property to fix the issue:   '-Dsolr.redaction.system.pattern=.*(password|secret|basicauth).*'

Missing Encryption of Sensitive Data vulnerability in Apache Tomcat due to the fix for CVE-2026-29146 allowing the bypass of the EncryptInterceptor. This issue affects Apache Tomcat: 11.0.20, 10.1.53, 9.0.116. Users are recommended to upgrade to version 11.0.21, 10.1.54 or 9.0.117, which fix the issue.

Buffer Over-read vulnerability in Apache HTTP Server. This issue affects Apache HTTP Server: through 2.4.66. Users are recommended to upgrade to version 2.4.67, which fixes the issue.

Improper Encoding or Escaping of Output vulnerability in the JsonAccessLogValve component of Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.20, from 10.1.0-M1 through 10.1.53, from 9.0.40 through 9.0.116. Users are recommended to upgrade to version 11.0.21, 10.1.54 or 9.0.117 , which fix the issue.

Insertion of Sensitive Information into Log File vulnerability in the cloud membership for clustering component of Apache Tomcat exposed the Kubernetes bearer token. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.20, from 10.1.0-M1 through 10.1.53, from 9.0.13 through 9.0.116. Users are recommended to upgrade to version 11.0.21, 10.1.54 or 9.0.117, which fix the issue.

Use of Hard-coded Cryptographic Key vulnerability in Apache OpenMeetings. The remember-me cookie encryption key is set to default value in openmeetings.properties and not being auto-rotated. In case OM admin hasn't changed the default encryption key, an attacker who has stolen a cookie from a logged-in user can get full user credentials. This issue affects Apache OpenMeetings: from 6.1.0 before 9.0.0. Users are recommended to upgrade to version 9.0.0, which fixes the issue.
