{"cve":"CVE-2026-62264","nvd":{"published":"2026-10-30T19:18:32.827","modified":"2026-10-30T19:39:14.897","status":"Deferred","description":"PDF Reader MCP is a Model Context Protocol server for reading PDF documents. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200","CWE-287","CWE-306"],"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"],"products":[],"source":"nvd","synced_at":"2026-10-30T20:09:38.731693953+00:00"},"epss":null,"kev":null,"osv":[{"id":"GHSA-q344-5v34-gm84","url":"https://osv.dev/vulnerability/GHSA-q344-5v34-gm84","summary":"@sylphx/pdf-reader-mcp: HTTP transport accepts unauthenticated requests despite a configured MCP_API_KEY","modified":"2026-10-29T16:45:05.114119393Z","packages":[{"ecosystem":"npm","name":"@sylphx/pdf-reader-mcp","purl":"pkg:npm/%40sylphx/pdf-reader-mcp","ranges":[">=2.2.0 <3.0.1"],"fixed":["3.0.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
