{"id":"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.","aliases":["GHSA-6mmj-jhqj-6c6q"],"modified":"2026-07-15T01:49:21.507293626Z","published":"2026-07-08T20:32:14.897Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55542.json","unresolved_ranges":[{"extracted_events":[{"fixed":"8.5.1"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"GitHub_M","cwe_ids":["CWE-862"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/grokability/snipe-it","events":[{"introduced":"0"},{"fixed":"ded6515cbc27a28f07395da318483c2e96263259"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v8.4.0","v8.3.3","v8.3.2","v8.3.1","v8.3.0","v8.2.1","v8.2.0","v8.1.18","v8.1.17","v8.1.16","v8.1.15","v8.1.4","v8.1.3","v8.1.2","v8.1.1","v8.1.0","v8.0.4","v8.0.3","v8.0.2","v8.0.1","v7.1.15","v7.1.14","v7.0.13","v7.0.10","v7.0.9","v7.0.8","v7.0.7","v7.0.6","v7.0.5","v7.0.0-pre","v6.3.1","v6.3.0","v6.0.10","v6.0.6","v6.0.5","v6.0.4","v6.0.3","v6.0.1","v6.0.0","v6.0.0-RC-8","v6.0.0-GM","v6.0.0-RC-5","v6.0.0-RC-7","v6.0.0-RC-6","v6.0.0-RC-4","v6.0.0-RC-3","v6.0.0-RC-2","v6.0.0-RC-1","v5.1.8","v5.1.7","5.1.7","v5.1.6","v5.1.4","v5.1.3","v5.1.2","v5.1.1","v5.1.0","v5.0.12","v5.0.11","v5.0.10","v5.0.9","v5.0.8","v5.0.7","v5.0.6","v5.0.5","v5.0.0-beta-7-GM","v5.0.0-beta-6-GM","v5.0.0-beta-5","v5.0.0-beta-4","v5.0.0-beta-3.0","v4.9.4","v4.9.3","v4.9.2","v4.9.1","v4.9.0","v4.8.0","v4.7.8","v4.7.7","v4.7.5","v4.7.4","v4.7.3","v4.7.2","v4.7.0","v4.6.18","v4.6.17","v4.6.16","v4.6.15","v4.6.14","v4.6.13","v4.6.12","v4.6.11","v4.6.10","v4.6.9","v4.6.8","v4.6.7","v4.6.6","v4.6.5","v4.6.4","v4.6.3","v4.6.2","v4.6.1","v4.6.0","v4.5.0","v4.4.1","v4.4.0","v4.3.0","v4.2.0","v4.1.14","v4.1.13","v4.1.12","v4.1.11","v4.1.10","v4.1.9","v4.1.8","v4.1.7","v4.1.6","v4.1.5","v4.1.4","v4.1.3","v4.1.2","v4.1.1","v4.1.0","v4.0.15","v4.0.14","v4.0.13","v4.0.12","v4.0.11","v4.0.10","v4.0.9","v4.0.8","v4.0.7","v4.0.6","v4.0.5","v4.0.4","v4.0.3","v4.0.2","v4.0.1","v4.0","v3.6.6","v3.6.5","v4.0-alpha-2","v3.6.4","v3.6.3","v3.6.2","v3.6.1","v3.6.0","v3.5.2","v3.5.1","v3.5.0","v3.5.0-beta2","v3.5.0-beta","v3.4.0-beta","v3.4.0-alpha","v3.3.0-beta","3.2.0","v3.1.0","v3.0","v3.0-beta.3","v3.0-beta.1","v3.0.0-beta","v3.0-alpha2","v3.0-alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55542.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U"}]}
