{"id":"CVE-2026-77362","published":"2026-10-13T14:17:42.490","lastModified":"2026-10-16T16:00:33.533","description":"obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, bridge tools do not consistently apply the read access-control list (ACL) to every returned field. The tasks_filter tool exposes group counts derived from denied notes, makemd_query passes unfiltered sibling result fields through, and list_templates exposes template paths and parsed user-function bodies without a read-whitelist check. An authenticated caller can consequently infer or read data from notes outside the caller's read ACL. Version 1.3.1 fixes the vulnerability by filtering path-attributable fields and applying the read whitelist to list_templates.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-200","CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://github.com/The-40-Thieves/obsidian-tc/commit/5ab2109274acf0070601fa71a62b14ddc9652309","tags":[]},{"url":"https://github.com/The-40-Thieves/obsidian-tc/pull/75","tags":[]},{"url":"https://github.com/The-40-Thieves/obsidian-tc/releases/tag/v1.3.1","tags":[]},{"url":"https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-43r2-c7g8-prc8","tags":[]}],"exploitRefs":[{"url":"https://github.com/The-40-Thieves/obsidian-tc/commit/5ab2109274acf0070601fa71a62b14ddc9652309","tags":[]},{"url":"https://github.com/The-40-Thieves/obsidian-tc/pull/75","tags":[]},{"url":"https://github.com/The-40-Thieves/obsidian-tc/releases/tag/v1.3.1","tags":[]},{"url":"https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-43r2-c7g8-prc8","tags":[]}],"hasPoc":true,"ai":null}
