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.","state":0,"publishedAt":"2026-10-13T14:17:42.343+00:00","modifiedAt":"2026-10-16T22:17:55.79+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","score":4.7,"severity":"MEDIUM"}],"references":["https://github.com/The-40-Thieves/obsidian-tc/commit/c81d1687e2cfec98a0d8bc5038c029f41ea9c920","https://github.com/The-40-Thieves/obsidian-tc/pull/76","https://github.com/The-40-Thieves/obsidian-tc/releases/tag/v1.3.1","https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-c5xx-h28h-f682"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77361","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-59","CWE-863"],"productCriteria":[],"sourceDates":{"published":"2026-10-13T14:17:42.343","lastModified":"2026-10-16T22:17:55.790"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
