{"id":"CVE-2026-8629","summary":"Crabbox \u003c v0.12.0 Privilege Escalation via Agent Ticket Endpoints","details":"Crabbox prior to v0.12.0 contains a privilege escalation vulnerability that allows users with shared visibility-only access to obtain Code, WebVNC, and Egress agent tickets by sending POST requests to ticket endpoints. Attackers can exploit insufficient access control checks on the /v1/leases/:id/code/ticket, /v1/leases/:id/webvnc/ticket, and /v1/leases/:id/egress/ticket endpoints to obtain bridge-agent tickets and impersonate trusted lease-side bridges despite having only visibility permissions.","modified":"2026-07-16T03:30:57.539493674Z","published":"2026-05-14T19:11:59.982Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/8xxx/CVE-2026-8629.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/8xxx/CVE-2026-8629.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/crabbox/releases/tag/v0.12.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-8629"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/crabbox-privilege-escalation-via-agent-ticket-endpoints"},{"type":"REPORT","url":"https://github.com/openclaw/crabbox/pull/71"},{"type":"FIX","url":"https://github.com/openclaw/crabbox/commit/95cb30dc7dbaa1fef690a42ef6ac1cb6e307a191"},{"type":"PACKAGE","url":"https://github.com/openclaw/crabbox"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/crabbox","events":[{"introduced":"0"},{"fixed":"95cb30dc7dbaa1fef690a42ef6ac1cb6e307a191"},{"fixed":"2e842f89e5d7679a3726527b36f18692d4e6e155"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.12.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.11.0","v0.10.0","v0.9.0","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-2026-8629.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:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
