Fluentd collects events from various data sources and writes them to files, RDBMS, NoSQL, IaaS, SaaS, Hadoop and so on. A remote code execution (RCE) vulnerability in non-default configurations of Fluentd allows unauthenticated attackers to execute arbitrary code via specially crafted JSON payloads. Fluentd setups are only affected if the environment variable `FLUENT_OJ_OPTION_MODE` is explicitly set to `object`. Please note: The option FLUENT_OJ_OPTION_MODE was introduced in Fluentd version 1.13.2. Earlier versions of Fluentd are not affected by this vulnerability. This issue was patched in version 1.15.3. As a workaround do not use `FLUENT_OJ_OPTION_MODE=object`.

An issue was discovered in Zammad before 4.1.1. The Form functionality allows remote code execution because deserialization is mishandled.

Sitecore XP 7.5 Initial Release to Sitecore XP 8.2 Update-7 is vulnerable to an insecure deserialization attack where it is possible to achieve remote command execution on the machine. No authentication or special configuration is required to exploit this vulnerability.

Pre-authentication deserialization of untrusted data vulnerability has been identified in the SMA1000 Appliance Management Console (AMC) and Central Management Console (CMC), which in specific conditions could potentially enable a remote unauthenticated attacker to execute arbitrary OS commands.

Rack::Session is a session management implementation for Rack. From 2.0.0 to before 2.1.2, Rack::Session::Cookie incorrectly handles decryption failures when configured with secrets:. If cookie decryption fails, the implementation falls back to a default decoder instead of rejecting the cookie. This allows an unauthenticated attacker to supply a crafted session cookie that is accepted as valid session data without knowledge of any configured secret. Because this mechanism is used to load session state, an attacker can manipulate session contents and potentially gain unauthorized access. This vulnerability is fixed in 2.1.2.

An Unsafe Deserialization vulnerability exists in the worker services of the Apache Storm supervisor server allowing pre-auth Remote Code Execution (RCE). Apache Storm 2.2.x users should upgrade to version 2.2.1 or 2.3.0. Apache Storm 2.1.x users should upgrade to version 2.1.1. Apache Storm 1.x users should upgrade to version 1.2.4

cwlviewer is a web application to view and share Common Workflow Language workflows. Versions prior to 1.3.1 contain a Deserialization of Untrusted Data vulnerability. Commit number f6066f09edb70033a2ce80200e9fa9e70a5c29de (dated 2021-09-30) contains a patch. There are no available workarounds aside from installing the patch. The SnakeYaml constructor, by default, allows any data to be parsed. To fix the issue the object needs to be created with a `SafeConstructor` object, as seen in the patch.

Deserialization of Untrusted Data in the Sitecore.Security.AntiCSRF (aka anti CSRF) module in Sitecore CMS 7.0 to 7.2 and Sitecore XP 7.5 to 8.2 allows an unauthenticated attacker to execute arbitrary code by sending a serialized .NET object in the HTTP POST parameter __CSRFTOKEN.

The fix for CVE-2026-41635 was not applied to the 2.1.X and 2.2.X branches. Here was the original issue description: Apache MINA's AbstractIoBuffer.resolveClass() contains two branches, one of them (for static classes or primitive types) does not check the class at all, bypassing the classname allowlist and allowing arbitrary code to be executed. The fix checks if the class is present in the accepted class filter before calling Class.forName(). Affected versions are Apache MINA 2.1.0 <= 2.1.11, and 2.2.0 <= 2.2.6. The problem is resolved in Apache MINA 2.1.12, and 2.2.7 by applying the classname allowlist earlier. Affected are applications using Apache MINA that call IoBuffer.getObject(). Applications using Apache MINA are advised to upgrade.

The Popup Builder plugin 2.2.8 through 2.6.7.6 for WordPress is vulnerable to SQL injection (in the sgImportPopups function in sg_popup_ajax.php) via PHP Deserialization on attacker-controlled data with the attachmentUrl POST variable. This allows creation of an arbitrary WordPress Administrator account, leading to possible Remote Code Execution because Administrators can run PHP code on Wordpress instances. (This issue has been fixed in the 3.x branch of popup-builder.)

FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to com.ibatis.sqlmap.engine.transaction.jta.JtaTransactionConfig (aka ibatis-sqlmap).

All versions of bson before 1.1.4 are vulnerable to Deserialization of Untrusted Data. The package will ignore an unknown value for an object's _bsotype, leading to cases where an object is serialized as a document rather than the intended BSON type.

A deserialization of untrusted data vulnernerability exists in rails < 5.2.4.3, rails < 6.0.3.1 that can allow an attacker to unmarshal user-provided objects in MemCacheStore and RedisCacheStore potentially resulting in an RCE.

Deserialization of Untrusted Data in the BVMS Mobile Video Service (BVMS MVS) allows an unauthenticated remote attacker to execute arbitrary code on the system. This affects Bosch BVMS versions 10.0 <= 10.0.0.1225, 9.0 <= 9.0.0.827, 8.0 <= 8.0.0.329 and 7.5 and older. This affects Bosch DIVAR IP 3000 and DIVAR IP 7000 if a vulnerable BVMS version is installed.

Pachno 1.0.6 contains a deserialization vulnerability that allows unauthenticated attackers to execute arbitrary code by injecting malicious serialized objects into cache files. Attackers can write PHP object payloads to world-writable cache files with predictable names in the cache directory, which are unserialized during framework bootstrap before authentication checks occur.

Unsafe YAML deserialization in yaml.Loader in transmute-core before 1.13.5 allows attackers to execute arbitrary Python code.

The food-and-drink-menu plugin through 2.2.0 for WordPress allows remote attackers to execute arbitrary code because of an unserialize operation on the fdm_cart cookie in load_cart_from_cookie in includes/class-cart-manager.php.

The CoDesigner WooCommerce Builder for Elementor – Customize Checkout, Shop, Email, Products & More plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.4.1 via deserialization of untrusted input from the recently_viewed_products cookie. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

Unauthenticated PHP Object Injection in Elementra <= 1.0.9 versions.

DomPDF before version 2.0.0 is vulnerable to PHAR deserialization due to a lack of checking on the protocol before passing it into the file_get_contents() function. An attacker who can upload files of any type to the server can pass in the phar:// protocol to unserialize the uploaded file and instantiate arbitrary PHP objects. This can lead to remote code execution, especially when DOMPdf is used with frameworks with documented POP chains like Laravel or vulnerable developer code.

IBM MQ 7.5, 8.0, 9.0, 9.1, 9.2 LTS, and 9.2 CD could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe deserialization of trusted data. An attacker could exploit this vulnerability to execute arbitrary code on the system. IBM X-Force ID: 186509.

IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 could allow a remote attacker to execute arbitrary code on the system with a specially-crafted sequence of serialized objects from untrusted sources. IBM X-Force ID: 184585.

The wp-hotel-booking plugin through 1.10.2 for WordPress allows remote attackers to execute arbitrary code because of an unserialize operation on the thimpress_hotel_booking_1 cookie in load in includes/class-wphb-sessions.php.

PraisonAI is a multi-agent teams system. Prior to 4.5.115, the AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags (such as !!js/function and !!js/undefined). This allows an attacker to craft a malicious YAML file that, when parsed, executes arbitrary JavaScript code. An attacker can exploit this vulnerability by uploading a malicious agent definition file via the API endpoint, leading to remote code execution (RCE) on the server. This vulnerability is fixed in 4.5.115.

Magento versions 2.3.3 and earlier, 2.2.10 and earlier, 1.14.4.3 and earlier, and 1.9.4.3 and earlier have a deserialization of untrusted data vulnerability. Successful exploitation could lead to arbitrary code execution.

phpMussel from versions 1.0.0 and less than 1.6.0 has an unserialization vulnerability in PHP's phar wrapper. Uploading a specially crafted file to an affected version allows arbitrary code execution (discovered, tested, and confirmed by myself), so the risk factor should be regarded as very high. Newer phpMussel versions don't use PHP's phar wrapper, and are therefore unaffected. This has been fixed in version 1.6.0.

The Java OpenWire protocol marshaller is vulnerable to Remote Code Execution. This vulnerability may allow a remote attacker with network access to either a Java-based OpenWire broker or client to run arbitrary shell commands by manipulating serialized class types in the OpenWire protocol to cause either the client or the broker (respectively) to instantiate any class on the classpath. Users are recommended to upgrade both brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3 which fixes this issue.

Apache jUDDI uses several classes related to Java's Remote Method Invocation (RMI) which (as an extension to UDDI) provides an alternate transport for accessing UDDI services. RMI uses the default Java serialization mechanism to pass parameters in RMI invocations. A remote attacker can send a malicious serialized object to the above RMI entries. The objects get deserialized without any check on the incoming data. In the worst case, it may let the attacker run arbitrary code remotely. For both jUDDI web service applications and jUDDI clients, the usage of RMI is disabled by default. Since this is an optional feature and an extension to the UDDI protocol, the likelihood of impact is low. Starting with 3.3.10, all RMI related code was removed.

IBM WebSphere Application Server 8.5 and 9.0 traditional could allow a remote attacker to execute arbitrary code on the system with a specially-crafted sequence of serialized objects. IBM X-Force ID: 181231.

The GDPR CCPA Compliance Support plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.3 via deserialization of untrusted input "njt_gdpr_allow_permissions" value. This allows unauthenticated attackers to inject a PHP Object.

The Live Auction Cockpit in SAP Supplier Relationship Management (SRM) uses a deprecated java applet component, which allows an unauthenticated attacker to send malicious payload request in a specific encoding format. The servlet will then decode this malicious request which will result in deserialization of data in the application leading to execution of arbitrary OS command on target as SAP Administrator. This vulnerability has High impact on confidentiality, integrity, and availability of the application.

The Newsletter Manager plugin for WordPress is vulnerable to insecure deserialization in versions up to, and including, 1.5.1. This is due to unsanitized input from the 'customFieldsDetails' parameter being passed through a deserialization function. This potentially makes it possible for unauthenticated attackers to inject a serialized PHP object.

The Ultimate Reviews plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.1.32 via deserialization of untrusted input in several vulnerable functions. This allows unauthenticated attackers to inject a PHP Object. No POP chain is present in the vulnerable plugin.

Consensys gnark-crypto through 0.11.2 allows Signature Malleability. This occurs because deserialisation of EdDSA and ECDSA signatures does not ensure that the data is in a certain interval.

CraftCMS 3 vCard Plugin 1.0.0 contains a deserialization vulnerability that allows unauthenticated attackers to execute arbitrary PHP code through a crafted payload. Attackers can generate a malicious serialized payload that triggers remote code execution by exploiting the plugin's vCard download functionality with a specially crafted request.

PHPMailer 6.1.8 through 6.4.0 allows object injection through Phar Deserialization via addAttachment with a UNC pathname. NOTE: this is similar to CVE-2018-19296, but arose because 6.1.8 fixed a functionality problem in which UNC pathnames were always considered unreadable by PHPMailer, even in safe contexts. As an unintended side effect, this fix eliminated the code that blocked addAttachment exploitation.

ThinkPHP v6.0.8 was discovered to contain a deserialization vulnerability via the component vendor\league\flysystem-cached-adapter\src\Storage\Adapter.php.
