In versions 2.2.0 and later prior to 3.0.1, when `MCP_TRANSPORT=http` enables the opt-in HTTP server, `@sylphx/pdf-reader-mcp` reads `MCP_API_KEY` and logs that `X-API-Key` authentication is enabled but never validates the `X-API-Key` header on incoming requests. The `/mcp` endpoint consequently accepts unauthenticated clients. With the default bind address of `0.0.0.0`, any client able to reach the port can invoke every PDF tool and read any PDF the server process can open on the host, despite the misleading authentication-enabled startup log. URL-based sources additionally permit limited server-side request forgery; private and loopback destinations are blocked by default unless `--allow-private-ips` is set. The default `stdio` transport is unaffected. This issue is fixed in version 3.0.1.","state":0,"publishedAt":"2026-10-30T19:18:32.827+00:00","modifiedAt":"2026-11-06T18:18:16.043+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/SylphxAI/anymd/commit/4c35f72862d729301e3912ab8c8317d2828cf4c2","https://github.com/SylphxAI/anymd/pull/332","https://github.com/SylphxAI/anymd/security/advisories/GHSA-q344-5v34-gm84","https://github.com/SylphxAI/anymd/tree/v3.0.1"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62264","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-200","CWE-287","CWE-306"],"productCriteria":[],"sourceDates":{"published":"2026-10-30T19:18:32.827","lastModified":"2026-11-06T18:18:16.043"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
