{"id":"CVE-2026-71247","summary":"Documenso - Assistant Recipient Can Forge Another Signer's Signature in Sequential-Signing Documents","details":"Documenso's sign-field-with-token.ts, used by the live document-signing UI, allows a recipient with the ASSISTANT role to fetch and complete fields belonging to any later-or-equal-order, not-yet-signed recipient in the same envelope, with no restriction on field type. A newer V2 signing path (sign-envelope-field.ts) explicitly blocks assistants from completing SIGNATURE fields, and the project's own test suite comments confirm this guard is absent from the V1 path used here.","modified":"2026-08-28T11:30:17.712711766Z","published":"2026-08-05T10:56:59.954Z","database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71247.json","cna_assigner":"TuranSec"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71247.json"},{"type":"ADVISORY","url":"https://github.com/documenso/documenso"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71247"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/documenso/documenso","events":[{"introduced":"0"},{"last_affected":"f6bff1649b596360b7d272cdd596881b44c30af0"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"0"}]}}],"versions":["0","v0.9","before-prettier","0.9-developer-preview"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71247.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
