{"id":"CVE-2026-77362","summary":"obsidian-tc bridge tools expose data outside the read ACL","details":"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.","aliases":["GHSA-43r2-c7g8-prc8"],"modified":"2026-10-15T02:47:33.634745537Z","published":"2026-10-13T14:00:11.565Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-200","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77362.json"},"references":[{"type":"WEB","url":"https://github.com/The-40-Thieves/obsidian-tc/releases/tag/v1.3.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77362.json"},{"type":"ADVISORY","url":"https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-43r2-c7g8-prc8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77362"},{"type":"FIX","url":"https://github.com/The-40-Thieves/obsidian-tc/commit/5ab2109274acf0070601fa71a62b14ddc9652309"},{"type":"FIX","url":"https://github.com/The-40-Thieves/obsidian-tc/pull/75"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/the-40-thieves/obsidian-tc","events":[{"introduced":"0"},{"fixed":"5ab2109274acf0070601fa71a62b14ddc9652309"},{"fixed":"3956ed5173ebde7864c7d576c259e9e747b11d76"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.3.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.2.1","v1.0.2","v1.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-77362.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
