{"schema":"threatline.record/2","record":{"id":"CVE-2026-63630","aliases":["GHSA-cx8x-7rrr-r9x8"],"summary":"BentoPDF: Workflow Import Allows Unvalidated TSA URL Leading to PDF Hash Exfiltration via RFC 3161 Requests","details":"BentoPDF is a client-side PDF toolkit that is self hostable. In 2.8.6 and earlier, deserializeWorkflow() accepts the Timestamp node's tsaUrl control from imported JSON without schema or destination validation. When a user imports the crafted workflow and runs it against a PDF, timestampPdf() sends an RFC 3161 TimeStampReq containing the PDF's SHA-256 MessageImprint to the attacker-selected endpoint. The default self-hosted configuration does not set VITE_CORS_PROXY_URL, so the request bypasses the proxy's ALLOWED_TSA_HOSTS checks and is sent directly. The disclosed digest can confirm that a document matches a known file and can correlate the same document across users without revealing its contents. This vulnerability is fixed in 2.8.7.","categories":["Unclassified"],"product":"bentopdf","vendor":"alam00000","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-63630","source_modified_at":"2026-09-29T02:49:15.644Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"bentopdf","vendor":"alam00000","versions":[{"status":"affected","version":"< 2.8.7"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/alam00000/bentopdf/security/advisories/GHSA-cx8x-7rrr-r9x8","source_modified_at":"2026-08-23T12:55:12Z","fetched_at":"2026-10-23T19:00:29.328130Z","package":{"ecosystem":"other","name":"bentopdf"},"range":"<= v2.8.6"}],"fixed_versions":[],"cvss":3.4,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00309,"percentile":0.22497,"score_date":"2026-10-23"},"published_at":"2026-09-24T15:33:44.489Z","modified_at":"2026-09-29T02:49:15.644Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-63630","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T02:49:15.644Z"},{"source":"GitHub Advisory Database","url":"https://github.com/alam00000/bentopdf/security/advisories/GHSA-cx8x-7rrr-r9x8","fetched_at":"2026-10-23T19:00:29.328130Z","source_modified_at":"2026-08-23T12:55:12Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-63630","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/alam00000/bentopdf/security/advisories/GHSA-cx8x-7rrr-r9x8","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/alam00000/bentopdf/commit/b21f602cca972320bfffbf72e37df535313a6e48","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/alam00000/bentopdf/releases/tag/v2.8.7","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-29T02:48:51.526364Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-29T02:49:15.644Z","content_hash":"c53891f31bd278b14d50edd9390003a4b82c6bd9ac852fea215be8a86e34a376"}}
