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":"2026-10-13T14:00:39.982+00:00","modifiedAt":"2026-10-16T21:58:14.281+00:00","affected":[{"ecosystem":"Vendor product","name":"obsidian-tc","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"The-40-Thieves\",\n                    \"product\": \"obsidian-tc\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.3.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/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/releases/tag/v1.3.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77361","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77361","identifiers":["CVE-2026-77361"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
