{"id":"CVE-2026-72692","summary":"OpenSignLabs opensignserver - Missing Authorization","details":"A missing authorization vulnerability in OpenSignLabs opensignserver through 2.37.0 allows an unauthenticated remote attacker to irreversibly decline any in-flight document and forge the decline attribution to an arbitrary user via the declinedoc Parse cloud function. The function writes IsDeclined, DeclineReason, and a caller-supplied DeclineBy pointer without verifying the caller's identity, enabling workflow termination and evidentiary record falsification against any accessible document.","modified":"2026-08-28T11:30:24.725707067Z","published":"2026-08-10T11:59:14.935Z","database_specific":{"cna_assigner":"TuranSec","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72692.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72692.json"},{"type":"ADVISORY","url":"https://github.com/OpenSignLabs/OpenSign"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72692"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opensignlabs/opensign","events":[{"introduced":"0"},{"fixed":"a56b87a7020de74b0f7dda29d7ec3de382a456bb"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"last_affected":"2.37.0"},{"fixed":"2.37.0"}]}}],"versions":["v2.36.0","v2.35.0","v2.34.0","v2.33.0","v2.32.0","v2.31.0","v2.30.0","v2.29.2","v2.29.1","v2.29.0","v2.28.0","v2.27.2","v2.26.0","v2.25.0","v2.24.1","v2.23.0","v2.22.0","v2.21.1","v2.21.0","v2.20.1","v2.20.0","v2.19.2","v2.19.1","v2.19.0","v2.18.0","v2.17.0","v2.16.0","v2.15.0","v2.13.0","v2.7.0","v2.12.0","v2.6.0","v2.5.0","v2.4.1","v2.4.0","v2.3.3","v2.3.2","v2.3.1","v2.3.0","v2.2.0","v2.1.2","v2.1.1","v2.1.0","v2.0.0","v1.8.1","v1.8.0","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.2","v1.6.1","v1.6.0","v1.5.8","v1.5.1","v1.5.0","v1.4.2","v1.4.1","v1.4.0-beta","1.3.2-beta","v1.3.1-beta","v1.3.0-beta","v1.2.2-beta","v1.2.1-beta","v1.2.0-beta","v1.1.1-beta","v1.1.0-beta","v1.0.7-beta","v1.0.6-beta","v1.0.5-beta","v1.0.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72692.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
