On filesystem drivers that return false instead of throwing on a write failure (for example the local disk with restrictive permissions, S3 with expired credentials, or a storage backend that is out of quota), execution continues into $acceptance->accept(), which sets accepted_at and the signature_filename/eula_filename fields, creates the 'accepted' action-log entry, and dispatches completion notifications even though the evidence files were never stored. The result is an acceptance record marked complete whose supporting evidence files do not exist, yielding a materially incomplete compliance artifact for EULA acknowledgement or equipment-receipt workflows. The condition is triggered when an authenticated user completes an acceptance while the storage backend is silently failing writes; an attacker cannot directly force the storage backend into that state. Fixed in Snipe-IT 8.7.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":2.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-252"],"references":["https://github.com/grokability/snipe-it/security/advisories/GHSA-h543-58f9-v6mj","https://www.vulncheck.com/advisories/snipe-it-before-8.7.0-acceptance-finalization-without-stored-evidence"],"products":["snipeitapp:snipe-it"],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-86739","score":0.00357,"percentile":0.29403,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
