Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 3.5.14, 4.0.10, 4.1.8, and 4.2.0-rc2, under certain circumstances, attackers can exploit a flaw in domain name normalization to spoof domains they do not own. Versions 3.5.14, 4.0.10, 4.1.8, and 4.2.0-rc2 contain a patch for this issue.

Mastodon is a free, open-source social network server based on ActivityPub. Prior to v4.5.9, v4.4.16, and v4.3.22, Mastodon allows restricting new user sign-up based on e-mail domain names, and performs basic validation on e-mail addresses, but fails to restrict characters that are interpreted differently by some mailing servers. This vulnerability is fixed in v4.5.9, v4.4.16, and v4.3.22.

Mastodon is a free, open-source social network server based on ActivityPub. Mastodon allows server administrators to suspend remote users to prevent interactions. However, some logic errors allow already-known posts from such suspended users to appear in timelines if boosted. Furthermore, under certain circumstances, previously-unknown posts from suspended users can be processed. This issue allows old posts from suspended users to occasionally end up on timelines on all Mastodon versions. Additionally, on Mastodon versions from v4.5.0 to v4.5.4, v4.4.5 to v4.4.11, v4.3.13 to v4.3.17, and v4.2.26 to v4.2.29, remote suspended users can partially bypass the suspension to get new posts in. Mastodon versions v4.5.5, v4.4.12, v4.3.18 are patched.

Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 4.5.5, 4.4.12, and 4.3.18, an insecure direct object reference in the web push subscription update endpoint lets any authenticated user update another user's push subscription by guessing or obtaining the numeric subscription id. This can be used to disrupt push notifications for other users and also leaks the web push subscription endpoint. Any user with a web push subscription is impacted, because another authenticated user can tamper with their push subscription settings if they can guess or obtain the subscription id. This allows an attacker to disrupt push notifications by changing the policy (whether to filter notifications from non-followers or non-followed users) and subscribed notification types of their victims. Additionally, the endpoint returns the subscription object, which includes the push notification endpoint for this subscription, but not its keypair. Mastodon versions v4.5.5, v4.4.12, v4.3.18 are patched.

Mastodon is a free, open-source social network server based on ActivityPub. In versions on the 4.5.x branch prior to 4.5.8 and on the 4.4.x branch prior to 4.4.15, an attacker that knows of a quote before it has reached a server can prevent it from being correctly processed on that server. The vulnerability has been patched in Mastodon 4.5.8 and 4.4.15. Mastodon 4.3 and earlier are not affected because they do not support quotes.

Inappropriate authorization vulnerability in the system apps. Successful exploitation of this vulnerability may affect service integrity.

Misskey is an open source, decentralized microblogging platform. Misskey doesn't perform proper normalization on the JSON structures of incoming signed ActivityPub activity objects before processing them, allowing threat actors to spoof the contents of signed activities and impersonate the authors of the original activities. This vulnerability is fixed in 2024.5.0.

asterisk allows calls on prohibited networks

Hertzbeat is an open source, real-time monitoring system with custom-monitoring, high performance cluster, prometheus-like and agentless. Hertzbeat versions 1.20 and prior have a permission bypass vulnerability. System authentication can be bypassed and invoke interfaces without authorization. Version 1.2.1 contains a patch for this issue.

A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3). Affected devices load firmware updates without checking the authenticity. Furthermore the integrity of the unencrypted firmware is only verified by a non-cryptographic method. This could allow an attacker to manipulate a firmware update and flash it to the device.

A CWE-345: Insufficient Verification of Data Authenticity vulnerability exists that could cause loading of unauthorized firmware images due to improper verification of the firmware signature. Affected Products: X80 advanced RTU Communication Module (BMENOR2200H) (V2.01 and later), OPC UA Modicon Communication Module (BMENUA0100) (V1.10 and prior)

A flaw was found in OpenShift API, as admission checks do not enforce "custom-host" permissions. This issue could allow an attacker to violate the boundaries, as permissions will not be applied.

An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) (with TEEGRIS) software. Secure Folder does not properly restrict use of Android Debug Bridge (adb) for arbitrary installations. The Samsung ID is SVE-2020-17369 (June 2020).

DNSSEC validation is not performed correctly. An attacker can cause this package to report successful validation for invalid, attacker-controlled records. Root DNSSEC public keys are not validated, permitting an attacker to present a self-signed root key and delegation chain.

In GitLab versions prior to 13.2.10, 13.3.7 and 13.4.2, improper authorization checks allow a non-member of a project/group to change the confidentiality attribute of issue via mutation GraphQL query

An intent redirection vulnerability in the Mi Browser product. This vulnerability is caused by the Mi Browser does not verify the validity of the incoming data. Attackers can perform sensitive operations by exploiting this.

RubyGems is a package registry used to supply software for the Ruby language ecosystem. An ordering mistake in the code that accepts gem uploads allowed some gems (with platforms ending in numbers, like `arm64-darwin-21`) to be temporarily replaced in the CDN cache by a malicious package. The bug has been patched, and is believed to have never been exploited, based on an extensive review of logs and existing gems by rubygems. The easiest way to ensure that an application has not been exploited by this vulnerability is to verify all downloaded .gems checksums match the checksum recorded in the RubyGems.org database. RubyGems.org has been patched and is no longer vulnerable to this issue.

On Verizon 5G Home LVSKIHP OutDoorUnit (ODU) 3.33.101.0 devices, the RPC endpoint crtc_fw_upgrade provides a means of provisioning a firmware update for the device. /lib/functions/wnc_jsonsh/wnc_crtc_fw.sh has no cryptographic validation of the image, thus allowing an attacker to modify the installed firmware.

Adobe Commerce versions 2.4.9-beta1, 2.4.8-p4, 2.4.7-p9, 2.4.6-p14, 2.4.5-p16, 2.4.4-p17 and earlier are affected by an Incorrect Authorization vulnerability that could result in a Security feature bypass. An attacker could leverage this vulnerability to bypass security measures and gain unauthorized write access. Exploitation of this issue does not require user interaction.

Documents formed using data: URLs in an OBJECT element failed to inherit the CSP of the creating context. This allowed the execution of scripts that should have been blocked, albeit with a unique opaque origin. This vulnerability affects Firefox < 76.

OneUptime is a solution for monitoring and managing online services. Prior to version 10.0.34, the WhatsApp POST webhook handler (/notification/whatsapp/webhook) processes incoming status update events without verifying the Meta/WhatsApp X-Hub-Signature-256 HMAC signature, allowing any unauthenticated attacker to send forged webhook payloads that manipulate notification delivery status records, suppress alerts, and corrupt audit trails. The codebase already implements proper signature verification for Slack webhooks. This issue has been patched in version 10.0.34.

Authorization vulnerability in the BootLoader module. Successful exploitation of this vulnerability may affect service integrity.

The VerifiedBoot module has a vulnerability that may cause authentication errors.Successful exploitation of this vulnerability may affect integrity.

An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) software. Attackers can trigger an update to arbitrary touch-screen firmware. The Samsung ID is SVE-2019-16013 (March 2020).

xml-security is a library that implements XML signatures and encryption. Validation of an XML signature requires verification that the hash value of the related XML-document matches a specific DigestValue-value, but also that the cryptographic signature on the SignedInfo-tree (the one that contains the DigestValue) verifies and matches a trusted public key. If an attacker somehow (i.e. by exploiting a bug in PHP's canonicalization function) manages to manipulate the canonicalized version's DigestValue, it would be possible to forge the signature. This issue has been patched in version 1.6.12 and 5.0.0-alpha.13.

A vulnerability was found in mod_wsgi. The X-Client-IP header is not removed from a request from an untrusted proxy, allowing an attacker to pass the X-Client-IP header to the target WSGI application because the condition to remove it is missing.

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory.

EOSIO batdappboomx v327c04cf has an Access-control vulnerability in the `transfer` function of the smart contract which allows remote attackers to win the cryptocurrency without paying ticket fee via the `std::string memo` parameter.

Heimdall is a cloud native Identity Aware Proxy and Access Control Decision service. When using Heimdall in envoy gRPC decision API mode with versions 0.7.0-alpha through 0.17.10, wrong encoding of the query URL string allows rules with non-wildcard path expressions to be bypassed. Envoy splits the requested URL into parts, and sends the parts individually to Heimdall. Although query and path are present in the API, the query field is documented to be always empty and the URL query is included in the path field. The implementation uses go's url library to reconstruct the url which automatically encodes special characters in the path. As a consequence, a parameter like /mypath?foo=bar to Path is escaped into /mypath%3Ffoo=bar. Subsequently, a rule matching /mypath no longer matches and is bypassed. The issue can only lead to unintended access if Heimdall is configured with an "allow all" default rule. Since v0.16.0, Heimdall enforces secure defaults and refuses to start with such a configuration unless this enforcement is explicitly disabled, e.g. via --insecure-skip-secure-default-rule-enforcement or the broader --insecure flag. This issue has been fixed in version 0.17.11.

When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity check. Impacts: This vulnerability affects all users using the experimental policy mechanism in all active release lines: 18.x and, 20.x. Please note that at the time this CVE was issued, the policy mechanism is an experimental feature of Node.js.

A vulnerability has been identified in SIMATIC Drive Controller family (All versions), SIMATIC ET 200SP Open Controller CPU 1515SP PC (incl. SIPLUS variants) (All versions), SIMATIC ET 200SP Open Controller CPU 1515SP PC2 (incl. SIPLUS variants) (All versions < V20.8), SIMATIC ET 200SP Open Controller CPU 1515SP PC2 (incl. SIPLUS variants) (All versions >= V20.8), SIMATIC S7-1200 CPU family (incl. SIPLUS variants) (All versions < V4.4.0), SIMATIC S7-1200 CPU family (incl. SIPLUS variants) (All versions >= V4.4.0), SIMATIC S7-1500 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions < V2.8.1), SIMATIC S7-1500 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions >= V2.8.1), SIMATIC S7-1500 Software Controller (All versions < V20.8), SIMATIC S7-1500 Software Controller (All versions >= V20.8), SIMATIC S7-PLCSIM Advanced (All versions < V3.0), SIMATIC S7-PLCSIM Advanced (All versions >= V3.0). An attacker with network access to port 102/tcp could potentially modify the user program on the PLC in a way that the running code is different from the source code which is stored on the device. An attacker must have network access to affected devices and must be able to perform changes to the user program. The vulnerability could impact the perceived integrity of the user program stored on the CPU. An engineer that tries to obtain the code of the user program running on the device, can receive different source code that is not actually running on the device.

Syltek application before its 10.22.00 version, does not correctly check that a product ID has a valid payment associated to it. This could allow an attacker to forge a request and bypass the payment system by marking items as payed without any verification.

Certifi is a curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. Certifi prior to version 2023.07.22 recognizes "e-Tugra" root certificates. e-Tugra's root certificates were subject to an investigation prompted by reporting of security issues in their systems. Certifi 2023.07.22 removes root certificates from "e-Tugra" from the root store.

OpenFGA is an authorization/permission engine. OpenFGA v1.5.7 and v1.5.8 are vulnerable to authorization bypass when calling Check API with a model that uses `but not` and `from` expressions and a userset. Users should downgrade to v1.5.6 as soon as possible. This downgrade is backward compatible. As of time of publication, a patch is not available but OpenFGA's maintainers are planning a patch for inclusion in a future release.

OpenClaw before 2026.4.27 contains an authorization bypass vulnerability in QQBot pre-dispatch slash commands that allows authenticated senders to skip allowFrom policy checks. Attackers can invoke slash commands before configured access control policies are applied, potentially triggering command handling from blocked senders depending on operator configuration.

In MediaWiki before 1.31.15, 1.32.x through 1.35.x before 1.35.3, and 1.36.x before 1.36.1, bots have certain unintended API access. When a bot account has a "sitewide block" applied, it is able to still "purge" pages through the MediaWiki Action API (which a "sitewide block" should have prevented).

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to version 1.6.4, Authlib’s JWS verification accepts tokens that declare unknown critical header parameters (crit), violating RFC 7515 “must‑understand” semantics. An attacker can craft a signed token with a critical header (for example, bork or cnf) that strict verifiers reject but Authlib accepts. In mixed‑language fleets, this enables split‑brain verification and can lead to policy bypass, replay, or privilege escalation. This issue has been patched in version 1.6.4.

In FreeBSD 13.0-STABLE before n245764-876ffe28796c, 12.2-STABLE before r369857, 13.0-RELEASE before p1, and 12.2-RELEASE before p7, a system call triggering a fault could cause SMAP protections to be disabled for the duration of the system call. This weakness could be combined with other kernel bugs to craft an exploit.

The auth_internal plugin in Tiny Tiny RSS (aka tt-rss) before 2021-03-12 allows an attacker to log in via the OTP code without a valid password. NOTE: this issue only affected the git master branch for a short time. However, all end users are explicitly directed to use the git master branch in production. Semantic version numbers such as 21.03 appear to exist, but are automatically generated from the year and month. They are not releases.

The Acexy Wireless-N WiFi Repeater REV 1.0 (28.08.06.1) Web management administrator password can be changed by sending a specially crafted HTTP GET request. The administrator username has to be known (default:admin) whereas no previous authentication is required.

On Arista Strata family products which have “TCAM profile” feature enabled when Port IPv4 access-list has a rule which matches on “vxlan” as protocol then that rule and subsequent rules ( rules declared after it in ACL ) do not match on IP protocol field as expected.

On affected Arista EOS platforms, if a VXLAN match rule exists in an IPv4 access-list that is applied to the ingress of an L2 or an L3 port/SVI, the VXLAN rule and subsequent ACL rules in that access list will ignore the specified IP protocol.

Clerk helps developers build user management. Applications that use the verifyWebhook() helper to verify incoming Clerk webhooks are susceptible to accepting improperly signed webhook events. The issue was resolved in @clerk/backend 2.4.0.

go-git is an extensible git implementation library written in pure Go. Prior to 5.19.0 and 6.0.0-alpha.3, go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object. Additionally, go-git’s commit signing and verification logic operates over commit data reconstructed from go-git’s parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository. This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed. This vulnerability is fixed in 5.19.0 and 6.0.0-alpha.3.

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. In versions 7.0.0 to before 10.0.1, DNN.PLATFORM allows a specially crafted request or proxy to be created that could bypass the design of DNN Login IP Filters allowing login attempts from IP Addresses not in the allow list. This issue has been patched in version 10.0.1.

Electric Coin Company Zcashd before 2.1.1-1 allows attackers to trigger consensus failure and double spending. A valid chain could be incorrectly rejected because timestamp requirements on block headers were not properly enforced.

An issue has been discovered in GitLab CE/EE affecting all versions starting from 13.8. GitLab was not properly validating authorisation tokens which resulted in GraphQL mutation being executed.

controllers/admin.js in Total.js CMS 13 allows remote attackers to execute arbitrary code via a POST to the /admin/api/widgets/ URI. This can be exploited in conjunction with CVE-2019-15954.
