CVE-2026-55582

mcp-shell is an MCP server for running shell commands securely, auditably, and on demand. Prior to 0.6.0, the default security.yaml allows /usr/bin/git, while security.go omits ! from containsShellMetacharacters and containsDangerousShellConstructs and applies no per-executable argument policy. A...

GHSA-74HP-MGGR-HV58 mcp-shell has a Secure Mode Allowlist Bypass via Git Shell Alias

Summary mcp-shell's "secure mode" is designed to restrict command execution to an allowlist of executables defined in security.yaml. The default configuration includes /usr/bin/git. The security validator in security.go blocks common shell metacharacters |&;$\ but omits !, which is the prefix Git...

libgit2: libgit2: Denial of Service due to heap out-of-bounds read from malicious Git server

A flaw was found in libgit2. A fixed-size string comparison in the setdata function within transports/smartpkt.c does not adequately verify the size of a network packet buffer. A remote attacker, operating a malicious Git server, can send a specially crafted packet-line capability buffer. This ca...
