CVE-2026-27896 1 Modelcontextprotocol 1 Go-sdk 2026-02-27 7.2 High
The Go MCP SDK used Go's standard encoding/json.Unmarshal for JSON-RPC and MCP protocol message parsing in versions prior to 1.3.1. Go's standard library performs case-insensitive matching of JSON keys to struct field tags — a field tagged json:"method" would also match "Method", "METHOD", etc. This violated the JSON-RPC 2.0 specification, which defines exact field names. A malicious MCP peer may have been able to send protocol messages with non-standard field casing that the SDK would silently accept. This had the potential for bypassing intermediary inspection and coss-implementation inconsistency. Go's standard JSON unmarshaling was replaced with a case-sensitive decoder in commit 7b8d81c. Users are advised to update to v1.3.1 to resolve this issue.
CVE-2026-27575 1 Go-vikunja 1 Vikunja 2026-02-27 9.1 Critical
Vikunja is an open-source self-hosted task management platform. Prior to version 2.0.0, the application allows users to set weak passwords (e.g., 1234, password) without enforcing minimum strength requirements. Additionally, active sessions remain valid after a user changes their password. An attacker who compromises an account (via brute-force or credential stuffing) can maintain persistent access even after the victim resets their password. Version 2.0.0 contains a fix.

The manipulation leads to improper authentication. The attack is possible to be carried out remotely. The attack is considered to have high complexity. The exploitability is assessed as difficult. The exploit has been disclosed publicly and may be used. The vendor was informed early via email. A separate report via bugbounty was rejected with the reason "This is by design. The user is responsible for host security".
CVE-2026-27976 1 Zed-industries 1 Zed 2026-02-27 8.8 High
Zed, a code editor, has an extension installer allows tar/gzip downloads. Prior to version 0.224.4, the tar extractor (`async_tar::Archive::unpack`) creates symlinks from the archive without validation, and the path guard (`writeable_path_from_extension`) only performs lexical prefix checks without resolving symlinks. An attacker can ship a tar that first creates a symlink inside the extension workdir pointing outside (e.g., `escape -> /`), then writes files through the symlink, causing writes to arbitrary host paths. This escapes the extension sandbox and enables code execution. Version 0.224.4 patches the issue.
CVE-2026-27974 1 Advplyr 1 Audiobookshelf 2026-02-27 4.8 Medium
Audiobookshelf is a self-hosted audiobook and podcast server. A cross-site scripting (XSS) vulnerability exists in versions prior to 0.12.0-beta of the Audiobookshelf mobile application that allows arbitrary JavaScript execution through malicious library metadata. Attackers with library modification privileges (or control over a malicious podcast RSS feed) can execute code in victim users' WebViews, potentially leading to session hijacking, data exfiltration, and unauthorized access to native device APIs. audiobookshelf-app version 0.12.0-beta fixes the issue.
CVE-2026-27973 1 Advplyr 1 Audiobookshelf 2026-02-27 4 Medium
Audiobookshelf is a self-hosted audiobook and podcast server. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 0.12.0-beta of the Audiobookshelf mobile application that allows arbitrary JavaScript execution through malicious library metadata. Attackers with library modification privileges can execute code in victim users' browsers/WebViews, potentially leading to session hijacking, data exfiltration, and unauthorized access to native device APIs. The issue is fixed in audiobookshelf-app version 0.12.0-beta, corresponding to audiobookshelf version 2.12.0.
CVE-2026-27946 1 Zitadel 1 Zitadel 2026-02-27 N/A
ZITADEL is an open source identity management platform. Prior to versions 4.11.1 and 3.4.7, a vulnerability in Zitadel's self-management capability allowed users to mark their email and phone as verified without going through an actual verification process. The patch in versions 4.11.1 and 3.4.7 resolves the issue by requiring the correct permission in case the verification flag is provided and only allows self-management of the email address and/or phone number itself. If an upgrade is not possible, an action (v2) could be used to prevent setting the verification flag on the own user.
CVE-2026-27938 2 Wordpress, Wpgraphql 2 Wordpress, Wpgraphql 2026-02-27 7.7 High
WPGraphQL provides a GraphQL API for WordPress sites. Prior to version 2.9.1, the `wp-graphql/wp-graphql` repository contains a GitHub Actions workflow (`release.yml`) vulnerable to OS command injection through direct use of `${{ github.event.pull_request.body }}` inside a `run:` shell block. When a pull request from `develop` to `master` is merged, the PR body is injected verbatim into a shell command, allowing arbitrary command execution on the Actions runner. Version 2.9.1 contains a fix for the vulnerability.
CVE-2026-27840 1 Zitadel 1 Zitadel 2026-02-27 4.3 Medium
ZITADEL is an open source identity management platform. Starting in version 2.31.0 and prior to versions 3.4.7 and 4.11.0, opaque OIDC access tokens in the v2 format truncated to 80 characters are still considered valid. Zitadel uses a symmetric AES encryption for opaque tokens. The cleartext payload is a concatenation of a couple of identifiers, such as a token ID and user ID. Internally Zitadel has 2 different versions of token payloads. v1 tokens are no longer created, but are still verified as to not invalidate existing session after upgrade. The cleartext payload has a format of `<token_id>:<user_id>`. v2 tokens distinguished further where the `token_id` is of the format `v2_<oidc_session_id>-at_<access_token_id>`. V1 token authZ/N session data is retrieved from the database using the (simple) `token_id` value and `user_id` value. The `user_id` (called `subject` in some parts of our code) was used as being the trusted user ID. V2 token authZ/N session data is retrieved from the database using the `oidc_session_id` and `access_token_id` and in this case the `user_id` from the token is ignored and taken from the session data in the database. By truncating the token to 80 chars, the user_id is now missing from the cleartext of the v2 token. The back-end still accepts this for above reasons. This issue is not considered exploitable, but may look awkward when reproduced. The patch in versions 4.11.0 and 3.4.7 resolves the issue by verifying the `user_id` from the token against the session data from the database. No known workarounds are available.
CVE-2026-27887 1 Spinframework 3 Containerd-shim-spin, Spin, Spinkube 2026-02-27 N/A
Spin is an open source developer tool for building and running serverless applications powered by WebAssembly. When Spin is configured to allow connections to a database or web server which could return responses of unbounded size (e.g. tables with many rows or large content bodies), Spin may in some cases attempt to buffer the entire response before delivering it to the guest, which can lead to the host process running out of memory, panicking, and crashing. In addition, a malicious guest application could incrementally insert a large number of rows or values into a database and then retrieve them all in a single query, leading to large host allocations. Spin 3.6.1, SpinKube 0.6.2, and `containerd-shim-spin` 0.22.1 have been patched to address the issue. As a workaround, configure Spin to only allow access to trusted databases and HTTP servers which limit response sizes.
CVE-2026-27795 1 Langchain-ai 1 Langchainjs 2026-02-27 4.1 Medium
LangChain is a framework for building LLM-powered applications. Prior to version 1.1.8, a redirect-based Server-Side Request Forgery (SSRF) bypass exists in `RecursiveUrlLoader` in `@langchain/community`. The loader validates the initial URL but allows the underlying fetch to follow redirects automatically, which permits a transition from a safe public URL to an internal or metadata endpoint without revalidation. This is a bypass of the SSRF protections introduced in 1.1.14 (CVE-2026-26019). Users should upgrade to `@langchain/community` 1.1.18, which validates every redirect hop by disabling automatic redirects and re-validating `Location` targets before following them. In this version, automatic redirects are disabled (`redirect: "manual"`), each 3xx `Location` is resolved and validated with `validateSafeUrl()` before the next request, and a maximum redirect limit prevents infinite loops.
CVE-2026-27794 1 Langchain-ai 1 Langgraph-checkpoint 2026-02-27 6.6 Medium
LangGraph Checkpoint defines the base interface for LangGraph checkpointers. Prior to version 4.0.0, a Remote Code Execution vulnerability exists in LangGraph's caching layer when applications enable cache backends that inherit from `BaseCache` and opt nodes into caching via `CachePolicy`. Prior to `langgraph-checkpoint` 4.0.0, `BaseCache` defaults to `JsonPlusSerializer(pickle_fallback=True)`. When msgpack serialization fails, cached values can be deserialized via `pickle.loads(...)`. Caching is not enabled by default. Applications are affected only when the application explicitly enables a cache backend (for example by passing `cache=...` to `StateGraph.compile(...)` or otherwise configuring a `BaseCache` implementation), one or more nodes opt into caching via `CachePolicy`, and the attacker can write to the cache backend (for example a network-accessible Redis instance with weak/no auth, shared cache infrastructure reachable by other tenants/services, or a writable SQLite cache file). An attacker must be able to write attacker-controlled bytes into the cache backend such that the LangGraph process later reads and deserializes them. This typically requires write access to a networked cache (for example a network-accessible Redis instance with weak/no auth or shared cache infrastructure reachable by other tenants/services) or write access to local cache storage (for example a writable SQLite cache file via permissive file permissions or a shared writable volume). Because exploitation requires write access to the cache storage layer, this is a post-compromise / post-access escalation vector. LangGraph Checkpoint 4.0.0 patches the issue.
CVE-2026-27727 1 Swaldman 1 Mchange-commons-java 2026-02-27 8.3 High
mchange-commons-java, a library that provides Java utilities, includes code that mirrors early implementations of JNDI functionality, including support for remote `factoryClassLocation` values, by which code can be downloaded and invoked within a running application. If an attacker can provoke an application to read a maliciously crafted `jaxax.naming.Reference` or serialized object, they can provoke the download and execution of malicious code. Implementations of this functionality within the JDK were disabled by default behind a System property that defaults to `false`, `com.sun.jndi.ldap.object.trustURLCodebase`. However, since mchange-commons-java includes an independent implementation of JNDI derefencing, libraries (such as c3p0) that resolve references via that implementation could be provoked to download and execute malicious code even after the JDK was hardened. Mirroring the JDK patch, mchange-commons-java's JNDI functionality is gated by configuration parameters that default to restrictive values starting in version 0.4.0. No known workarounds are available. Versions prior to 0.4.0 should be avoided on application CLASSPATHs.
CVE-2026-27704 1 Dart-lang 2 Flutter, Sdk 2026-02-27 N/A
The Dart and Flutter SDKs provide software development kits for the Dart programming language. In versions of the Dart SDK prior to 3.11.0 and the Flutter SDK prior to version 3.41.0, when the pub client (`dart pub` and `flutter pub`) extracts a package in the pub cache, a malicious package archive can have files extracted outside the destination directory in the `PUB_CACHE`. A fix has been landed in commit 26c6985c742593d081f8b58450f463a584a4203a. By normalizing the file path before writing file, the attacker can no longer traverse up via a symlink. This patch is released in Dart 3.11.0 and Flutter 3.41.0.vAll packages on pub.dev have been vetted for this vulnerability. New packages are no longer allowed to contain symlinks. The pub client itself doesn't upload symlinks, but duplicates the linked entry, and has been doing this for years. Those whose dependencies are all from pub.dev, third-party repositories trusted to not contain malicious code, or git dependencies are not affected by this vulnerability.
CVE-2026-27497 1 N8n 1 N8n 2026-02-27 N/A
n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, an authenticated user with permission to create or modify workflows could leverage the Merge node's SQL query mode to execute arbitrary code and write arbitrary files on the n8n server. The issues have been fixed in n8n versions 2.10.1, 2.9.3, and 1.123.22. Users should upgrade to one of these versions or later to remediate all known vulnerabilities. If upgrading is not immediately possible, administrators should consider the following temporary mitigations. Limit workflow creation and editing permissions to fully trusted users only, and/or disable the Merge node by adding `n8n-nodes-base.merge` to the `NODES_EXCLUDE` environment variable. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
CVE-2026-26985 1 Aces 1 Loris 2026-02-27 8.1 High
LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. Starting in version 24.0.0 and prior to versions 26.0.5, 27.0.2, and 28.0.0, an authenticated user with the appropriate authorization can read configuration files on the server by exploiting a path traversal vulnerability. Some of these files contain hard-coded credentials. The vulnerability allows an attacker to read configuration files containing hard-coded credentials. The attacker could then authenticate to the database or other services if those credentials are reused. The attacker must be authenticated and have the required permissions. However, the vulnerability is easy to exploit and the application source code is public. This problem is fixed in LORIS v26.0.5 and v27.0.2 and above, and v28.0.0 and above. As a workaround, the electrophysiogy_browser in LORIS can be disabled by an administrator using the module manager.
CVE-2026-2694 2 Stellarwp, Wordpress 2 The Events Calendar, Wordpress 2026-02-27 5.4 Medium
The The Events Calendar plugin for WordPress is vulnerable to unauthorized modification of data and loss of data due to an improper capability check on the 'can_edit' and 'can_delete' function in all versions up to, and including, 6.15.16. This makes it possible for authenticated attackers, with Contributor-level access and above, to update or trash events, organizers and venues via REST API.
CVE-2026-2636 1 Microsoft 5 Windows, Windows 11, Windows 11 23h2 and 2 more 2026-02-27 5.5 Medium
This vulnerability is caused by a CWE‑159: "Improper Handling of Invalid Use of Special Elements" weakness, which leads to an unrecoverable inconsistency in the CLFS.sys driver. This condition forces a call to the KeBugCheckEx function, allowing an unprivileged user to trigger a system crash. Microsoft silently fixed this vulnerability in the September 2025 cumulative update for Windows 11 2024 LTSC and Windows Server 2025. Windows 25H2 (released in September) was released with the patch. Windows 1123h2 and earlier versions remain vulnerable.
CVE-2026-2489 2 Readymadeweb, Wordpress 2 Tp2wp Importer, Wordpress 2026-02-27 4.4 Medium
The TP2WP Importer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Watched domains' textarea on the attachment importer settings page in all versions up to, and including, 1.1. This is due to insufficient input sanitization and output escaping when domains are saved via AJAX and rendered with echo implode() without esc_textarea(). This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the attachment importer settings page.
