{"id":"CVE-2026-55542","aliases":["GHSA-6mmj-jhqj-6c6q"],"url":"https://o3.security/vulnerability/CVE-2026-55542","summary":"Snipe-IT's S3 signature image retrieval lacks authorization before temporary URL","details":"Snipe-IT is an IT asset/license management system. Prior to version 8.6.1, Snipe-IT S3 signature image retrieval lacks authorization before temporary URL. On S3-backed deployments, authenticated users who know a signature filename can obtain a 5-minute signed S3 URL because the S3 branch returns before the `authorize()` call used by the local-file branch. Version 8.6.1 contains a patch.","published":"2026-07-08T20:32:14.897Z","modified":"2026-08-27T03:57:11.195819965Z","cvss":null,"epss":{"score":0.00281,"percentile":0.20654,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"snipe/snipe-it","fixedVersion":"8.5.1"}],"fix":{"url":"https://github.com/grokability/snipe-it/commit/ded6515cbc27a28f07395da318483c2e96263259","label":"grokability/snipe-it@ded6515"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55542.json"},{"type":"ADVISORY","url":"https://github.com/grokability/snipe-it/security/advisories/GHSA-6mmj-jhqj-6c6q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55542"},{"type":"FIX","url":"https://github.com/grokability/snipe-it/commit/ded6515cbc27a28f07395da318483c2e96263259"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T03:57:11.195819965Z"}}
