CVE-2026-19282Public exploit

Local command execution via unescaped commit hash

Published Aug 8, 2026 · Updated Aug 8, 2026

Command injection in LLM Memory MCP Server at commit f11dc8bcff3ff8cf943a2945f99ff3b0bdc8a6d0 allows local users to run OS commands. The auto.capture action passes its caller-controlled hash to GitHooksManager.getCommitInfo, which interpolates it into three execSync git show shell strings without validation or escaping. Exploitation requires an initialized Git repository and access to invoke the local MCP tool; injected commands run with the server process's privileges.
