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.","state":0,"publishedAt":"2026-09-24T15:33:44.489+00:00","modifiedAt":"2026-09-29T02:49:15.644+00:00","affected":[{"ecosystem":"Vendor product","name":"bentopdf","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"alam00000\",\n                    \"product\": \"bentopdf\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.8.7\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N","score":3.4,"severity":"LOW"}],"references":["https://github.com/alam00000/bentopdf/security/advisories/GHSA-cx8x-7rrr-r9x8","https://github.com/alam00000/bentopdf/commit/b21f602cca972320bfffbf72e37df535313a6e48","https://github.com/alam00000/bentopdf/releases/tag/v2.8.7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-63630","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-63630","identifiers":["CVE-2026-63630"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
