{"id":"CVE-2026-45223","summary":"Crabbox \u003c 0.9.0 Authentication Bypass via Admin Claim Injection","details":"Crabbox before 0.9.0 contains an authentication bypass vulnerability in the coordinator user-token verification path where the verifyUserToken() function fails to reject payloads containing an admin claim, allowing attackers to escalate privileges. An attacker with access to the shared non-admin token can craft a user-token payload with admin: true, sign it using HMAC-SHA256, and present it to admin-only coordinator routes to gain full coordinator admin access including lease visibility, pool state management, and forced release operations.","modified":"2026-07-16T03:31:06.015317990Z","published":"2026-05-11T18:12:45.838Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-290"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45223.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45223.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/crabbox/releases/tag/v0.9.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45223"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/crabbox-authentication-bypass-via-admin-claim-injection"},{"type":"REPORT","url":"https://github.com/openclaw/crabbox/pull/64"},{"type":"FIX","url":"https://github.com/openclaw/crabbox/commit/46079f6de7f10cf61bc47efebd0c143a41664898"},{"type":"PACKAGE","url":"https://github.com/openclaw/crabbox"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/crabbox","events":[{"introduced":"0"},{"fixed":"b5a3561fa77f8ebdce046bf54841283e96df05c0"},{"fixed":"46079f6de7f10cf61bc47efebd0c143a41664898"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"0.9.0"}]}}],"versions":["v0.8.0","v0.7.0","v0.6.0","v0.5.1","v0.5.0","v0.4.0","v0.3.1","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45223.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
