As a result, **any valid token could read, write, or delete any configured vault** by passing `input.vault`, defeating multi-tenant isolation across ~90 tool sites. (`resources/read` was the only surface that already guarded this.)\n\n### Patches\nFixed in **1.3.1** (the fix was developed on the `v1.3.0` tag, which never published to npm; 1.3.1 is the first published release with the fix). Upgrade to `>= 1.3.1`.\n\n### Workarounds\nRun a single vault per server process, or isolate each tenant on a separate process/credential.\n\n### Fix\nA central `input.vault === ctx.vaultId` guard was added in dispatch before the scope check.","state":0,"publishedAt":"2026-10-23T17:29:17+00:00","modifiedAt":"2026-10-23T17:45:03.913249+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:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"CRITICAL"}],"references":["https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-84c9-qqpq-2pq5","https://github.com/The-40-Thieves/obsidian-tc/pull/72","https://github.com/The-40-Thieves/obsidian-tc/commit/38b4992e87dc2715564236e1a42d005ab05a0194","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-2026-77366"],"sourceUrl":"https://github.com/advisories/GHSA-84c9-qqpq-2pq5","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-84c9-qqpq-2pq5","identifiers":["GHSA-84c9-qqpq-2pq5","CVE-2026-77366"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
