Claude Code Action: Malicious MCP Server Configuration in PRs Enables Remote Code Execution and Secret Exfiltration

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...

CVE-2026-45062

CVE-2026-45062 affects FrankenPHP (versions 1.11.2–1.12.2). The vulnerability arises in the CGI path splitting logic (splitPos in cgi.go), where fallback matching uses golang.org/x/text/search with ignore-case, and engages when the request path contains non-ASCII bytes. Two flaws enable an attack...
