{"id":"CVE-2026-63630","published":"2026-09-24T16:17:08.873","lastModified":"2026-09-29T03:17:16.803","description":"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.","cvssScore":3.4,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N","cwes":["CWE-201","CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/alam00000/bentopdf/commit/b21f602cca972320bfffbf72e37df535313a6e48","tags":[]},{"url":"https://github.com/alam00000/bentopdf/releases/tag/v2.8.7","tags":[]},{"url":"https://github.com/alam00000/bentopdf/security/advisories/GHSA-cx8x-7rrr-r9x8","tags":[]},{"url":"https://github.com/alam00000/bentopdf/security/advisories/GHSA-cx8x-7rrr-r9x8","tags":[]}],"exploitRefs":[{"url":"https://github.com/alam00000/bentopdf/commit/b21f602cca972320bfffbf72e37df535313a6e48","tags":[]},{"url":"https://github.com/alam00000/bentopdf/releases/tag/v2.8.7","tags":[]},{"url":"https://github.com/alam00000/bentopdf/security/advisories/GHSA-cx8x-7rrr-r9x8","tags":[]},{"url":"https://github.com/alam00000/bentopdf/security/advisories/GHSA-cx8x-7rrr-r9x8","tags":[]}],"hasPoc":true,"ai":null}
