A caller could read `.obsidian/plugins/*/data.json`, exfiltrating **plugin API keys and Obsidian Sync passwords** (live-reproduced), as well as any other in-vault file by path.\n\n### Patches\nFixed in **1.3.1**. Upgrade to `>= 1.3.1`. The default now denies `.obsidian`/`.git`/`.trash` on read/write/delete and honors `strictReadDefault` on the request path.\n\n### Workarounds\nSet an explicit `readPaths`/`writePaths` whitelist that excludes the control directories.","categories":["Libraries & packages"],"product":"obsidian-tc","vendor":"The-40-Thieves","ecosystem":"npm","affected_ranges":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-cvp8-vvgf-69q4","source_modified_at":"2026-10-23T17:28:42Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"obsidian-tc"},"range":"< 1.3.1"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-77364","source_modified_at":"2026-10-15T13:36:24.558Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"obsidian-tc","vendor":"The-40-Thieves","versions":[{"version":"< 1.3.1","status":"affected"}],"defaultStatus":null},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-cvp8-vvgf-69q4","source_modified_at":"2026-10-23T17:45:03.910674609Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"obsidian-tc","ecosystem":"npm","purl":"pkg:npm/obsidian-tc"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.3.1"}]}],"versions":[]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-cvp8-vvgf-69q4","source_modified_at":"2026-10-23T17:28:42Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"obsidian-tc"},"version":"1.3.1"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-cvp8-vvgf-69q4","source_modified_at":"2026-10-23T17:45:03.910674609Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"obsidian-tc","ecosystem":"npm","purl":"pkg:npm/obsidian-tc"},"version":"1.3.1"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00238,"percentile":0.14084,"score_date":"2026-10-23"},"published_at":"2026-10-12T17:52:51.653Z","modified_at":"2026-10-23T17:45:03.910674609Z","provenance":[{"source":"GitHub Advisory Database","url":"https://github.com/advisories/GHSA-cvp8-vvgf-69q4","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T17:28:42Z"},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-77364","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-15T13:36:24.558Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-cvp8-vvgf-69q4","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-23T17:45:03.910674609Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-77364","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["GitHub Advisory Database","CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-cvp8-vvgf-69q4","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/The-40-Thieves/obsidian-tc/pull/73","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/The-40-Thieves/obsidian-tc/commit/74de320ddea855e1dec47d67beabe88491149dab","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/The-40-Thieves/obsidian-tc/releases/tag/v1.3.1","tags":["x_refsource_MISC"]},{"url":"https://nvd.nist.gov/vuln/detail/cve-2026-77364","source":"GitHub Advisory Database"},{"url":"https://github.com/advisories/GHSA-cvp8-vvgf-69q4","source":"GitHub Advisory Database"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T13:36:13.647560Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-23T17:45:03.910674609Z","content_hash":"49f4d0da9e4b23543f6f477c7349e6961c2694a72cd31c2b87188addd7fd0996"}}
