Prior to 1.3.1, the Streamable HTTP transport does not validate the Host or Origin header or enable DNS-rebinding protection. When the documented loopback configuration uses auth.mode set to none, a malicious web page can send requests to the local MCP endpoint and receive unrestricted vault access through the http-local caller. Version 1.3.1 fixes the vulnerability by enabling host, origin, and DNS-rebinding validation.","state":0,"publishedAt":"2026-10-12T18:17:23.513+00:00","modifiedAt":"2026-10-16T20:04:29.76+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/The-40-Thieves/obsidian-tc/commit/6428bfe6fdfd43aa7b4b369be3aecd6a268fb928","https://github.com/The-40-Thieves/obsidian-tc/pull/74","https://github.com/The-40-Thieves/obsidian-tc/releases/tag/v1.3.1","https://github.com/The-40-Thieves/obsidian-tc/security/advisories/GHSA-pqh8-4pj7-32xx"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77363","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-346","CWE-1385"],"productCriteria":[],"sourceDates":{"published":"2026-10-12T18:17:23.513","lastModified":"2026-10-16T20:04:29.760"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
