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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"The-40-Thieves","product":"obsidian-tc","versions":[{"version":"< 1.3.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","baseScore":4.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-13T14:50:11.531996Z","id":"CVE-2026-77362","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-200"},{"lang":"en","value":"CWE-863"}]}],"references":[{"url":"https://github.com/The-40-Thieves/obsidian-tc/commit/5ab2109274acf0070601fa71a62b14ddc9652309","source":"security-advisories@github.com"},{"url":"https://github.com/The-40-Thieves/obsidian-tc/pull/75","source":"security-advisories@github.com"},{"url":"https://github.com/The-40-Thieves/obsidian-tc/releases/tag/v1.3.1","source":"security-advisories@github.com"},{"url":"https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-43r2-c7g8-prc8","source":"security-advisories@github.com"}]}
