obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, undefined readPaths and writePaths settings allow all paths, strictReadDefault does not protect direct requests, and the .obsidian, .git, and .trash control directories are excluded only during enumeration. An authenticated caller can directly read sensitive files such as .obsidian/plugins/*/data.json, potentially exposing plugin API keys, Obsidian Sync passwords, and other in-vault data. Version 1.3.1 fixes the vulnerability by denying the control directories by default and enforcing strictReadDefault on direct request paths.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
