Name of the Vulnerable Software and Affected Versions Amazon awslabs postgres-mcp-server versions prior to 1.1.7
Description An incomplete list of disallowed inputs in the SQL validation component allows an unauthenticated actor to modify data beyond the intended read-only scope. This occurs when crafted SQL is placed into the content submitted during an authenticated user's interaction with the MCP server, potentially enabling the actor to disable row security and alter data.
Recommendations Upgrade to version 1.1.7 or above.
