obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, read access-control list (ACL) checks use a lexical vault-relative path while containment checks use the resolved path. An in-vault symlink under an allowed glob that resolves into a denied folder can therefore bypass the read ACL and expose files in the denied folder. Exploitation requires an out-of-band-planted symlink and does not permit an escape from the vault root. Version 1.3.1 fixes the vulnerability by applying ACL checks to the resolved vault-relative path.
