An in-vault symlink placed under an allowed glob, whose realpath resolved into a denied folder, passed the read ACL — an intra-vault read-ACL-scope bypass. It requires an out-of-band-planted symlink (no MCP tool creates one) and is not a vault-root escape.\n\n### Patches\nFixed in **1.3.1**. Upgrade to `>= 1.3.1`. ACL enforcement now derives the realpath vault-relative path and feeds a single unified predicate at every site.\n\n### Workarounds\nDo not permit untrusted symlinks inside the vault.","state":0,"publishedAt":"2026-10-23T17:28:19+00:00","modifiedAt":"2026-10-23T17:45:03.9214441+00:00","affected":[{"ecosystem":"npm","name":"obsidian-tc","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.3.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-c5xx-h28h-f682","https://github.com/The-40-Thieves/obsidian-tc/pull/76","https://github.com/The-40-Thieves/obsidian-tc/commit/c81d1687e2cfec98a0d8bc5038c029f41ea9c920","https://github.com/The-40-Thieves/obsidian-tc","https://github.com/The-40-Thieves/obsidian-tc/releases/tag/v1.3.1","https://nvd.nist.gov/vuln/detail/cve-2026-77361"],"sourceUrl":"https://github.com/advisories/GHSA-c5xx-h28h-f682","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-c5xx-h28h-f682","identifiers":["GHSA-c5xx-h28h-f682","CVE-2026-77361"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
