{"id":"CVE-2026-86755","state":"PUBLISHED","title":"Snipe-IT 4.2.0 through 8.6.3 Permission Bypass via OAuth","description":"Snipe-IT versions 4.2.0 through 8.6.3 expose Laravel Passport's auto-registered personal-access-token routes (GET, POST, DELETE /oauth/personal-access-tokens*) with only 'web' and 'auth:web' middleware, without the self.api permission gate that Snipe-IT enforces on its own token endpoints (/account/api and /api/v1/account/personal-access-tokens). Any user with a valid web session and the corresponding CSRF token can POST to /oauth/personal-access-tokens and mint a long-lived bearer token for their own account, even when an administrator has denied the self.api permission. The issued token is still subject to existing per-endpoint authorization policies, so this is not a privilege escalation; it defeats the administrative control intended to block API/scripted access at the user's own permission level. Fixed in 8.7.0 (commit 3f74b8c), which registers overriding routes wrapped in the can:self.api middleware.","publishedAt":"2026-09-09T13:32:16.916Z","updatedAt":"2026-09-14T13:26:06.374Z","severity":{"score":5.3,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["grokability snipe-it"],"affected":[{"vendor":"grokability","product":"snipe-it","defaultStatus":"unaffected","versions":[{"version":"4.2.0","status":"affected","lessThanOrEqual":"8.7.2","versionType":"semver"}]}],"references":["https://github.com/grokability/snipe-it/security/advisories/GHSA-76pf-qf59-ff3q","https://www.vulncheck.com/advisories/snipe-it-4.2.0-through-8.6.3-permission-bypass-via-oauth"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/86xxx/CVE-2026-86755.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-86755","state":"PUBLISHED","datePublished":"2026-09-09T13:32:16.916Z","dateUpdated":"2026-09-14T13:26:06.374Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-08T11:32:11.096Z"},"containers":{"cna":{"title":"Snipe-IT 4.2.0 through 8.6.3 Permission Bypass via OAuth","descriptions":[{"lang":"en","value":"Snipe-IT versions 4.2.0 through 8.6.3 expose Laravel Passport's auto-registered personal-access-token routes (GET, POST, DELETE /oauth/personal-access-tokens*) with only 'web' and 'auth:web' middleware, without the self.api permission gate that Snipe-IT enforces on its own token endpoints (/account/api and /api/v1/account/personal-access-tokens).
