PYSEC-2026-2630 mcp-server-git : Path traversal in git_add allows staging files outside repository boundaries

In mcp-server-git versions prior to 2026.1.14, the gitadd tool did not validate that file paths provided in the files argument were within the repository boundaries. The tool used GitPython's repo.index.add, which did not enforce working-tree boundary checks for relative paths. As a result,...

PYSEC-2026-2051 Weblate command-line client susceptible to SSL verification skip

Impact The SSL verification would be skipped for some crafted URLs. Patches https://github.com/WeblateOrg/wlc/pull/1097 Workarounds Avoid using untrusted wlc configurations, as that might cause insecure connections. References This issue was reported to us by wh1zee via HackerOne...

PYSEC-2026-1623 mcp-server-git has missing path validation when using --repository flag

In mcp-server-git versions prior to 2025.12.18, when the server is started with the --repository flag to restrict operations to a specific repository path, it did not validate that repopath arguments in subsequent tool calls were actually within that configured path. This could allow tool calls t...

The Form Vibes – Database Manager for Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Contact Form 7 Form Field in all versions up to, and including, 1.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers ...

Authentication Bypass by Primary Weakness

Overview Affected versions of this package are vulnerable to Authentication Bypass by Primary Weakness in the STARTTLS process. An attacker can compromise the security of the TLS connection by exploiting a scenario where a new transfer reuses an existing live connection despite a mismatch in TLS...

Due to the combination of checking out PR head branches attacker-controlled, reading .mcp.json from the working directory via default setting sources, and unconditionally enabling all project MCP servers via enableAllProjectMcpServers, it was possible for an attacker who opened a PR containing a...

Claude Code: Sandbox Escape via Symlink Following Allows Arbitrary File Write Outside Workspace

Claude Code's sandbox did not prevent sandboxed processes from creating symlinks pointing to locations outside the workspace. When Claude Code subsequently wrote to a path within such a symlink, its unsandboxed process followed the symlink and wrote to the target location outside the workspace...

Weblate: Improper access control for the translation memory in API

Impact The translation memory API exposed unintended endpoints, which in turn didn't do proper access control. Patches https://github.com/WeblateOrg/weblate/pull/18513 Workarounds Blocking access to /api/memory/ in the HTTP server removes access to this feature. References This issue was reported...

HackerOne: CVE-2026-21637 TLS PSK/ALPN Callback Exceptions Bypass Error Handlers

CVE-2026-21637 is regarding a vulnerability in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths tlsClientError...

GHSA-MMGP-WC2J-QCV7 Claude Code has a Workspace Trust Dialog Bypass via Repo-Controlled Settings File

Claude Code resolved the permission mode from settings files, including the repo-controlled .claude/settings.json, before determining whether to display the workspace trust confirmation dialog. A malicious repository could set permissions.defaultMode to bypassPermissions in its committed...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in smb.c, which may reuse already freed memory from a previous SMB connection request. The window of opportunity to exploit this is small, and the region of memory exposed is small and out of the attacker's control...

GHSA-4Q92-RFM6-2CQX Claude Code has Permission Deny Bypass Through Symbolic Links

Claude Code failed to strictly enforce deny rules configured in settings.json when accessing files through symbolic links. If a user explicitly denied Claude Code access to a file such as /etc/passwd and Claude Code had access to a symbolic link pointing to that file, it was possible for Claude...

PT-2026-6858

Claude Code's bubblewrap sandboxing mechanism failed to properly protect the .claude/settings.json configuration file when it did not exist at startup. While the parent directory was mounted as writable and .claude/settings.local.json was explicitly protected with read-only constraints,...

Claude Code has a Command Injection in find Command Bypasses User Approval Prompt

Due to an error in command parsing, it was possible to bypass the Claude Code confirmation prompt to trigger execution of untrusted commands through the find command. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window. Users on standard Claude...

Claude Code has a Domain Validation Bypass which Allows Automatic Requests to Attacker-Controlled Domains

Claude Code contained insufficient URL validation in its trusted domain verification mechanism for WebFetch requests. The application used a startsWith function to validate trusted domains e.g., docs.python.org, modelcontextprotocol.io, this could have enabled attackers to register domains like...
