CVE-2026-8621: CWE-287 Improper Authentication in openclaw crabbox
Crabbox prior to v0.12.0 contains an authentication bypass vulnerability that allows non-admin shared-token callers to impersonate other owners or organizations by spoofing identity headers. Attackers can inject malicious X-Crabbox-Owner and X-Crabbox-Org headers in requests authenticated with a shared token to bypass authorization checks and access owner/org-scoped lease operations belonging to victim accounts.
AI Analysis
Technical Summary
CVE-2026-8621 describes an authentication bypass vulnerability in openclaw's Crabbox product before version 0.12.0. The flaw allows non-admin users authenticated via shared tokens to spoof identity headers (X-Crabbox-Owner and X-Crabbox-Org) in requests, enabling them to impersonate other owners or organizations. This bypasses authorization checks and grants unauthorized access to owner or organization-scoped lease operations belonging to other accounts. The vulnerability is due to improper authentication controls (CWE-287).
Potential Impact
Attackers with non-admin shared tokens can impersonate other owners or organizations by injecting spoofed identity headers, thereby bypassing authorization mechanisms. This leads to unauthorized access to lease operations scoped to victim owners or organizations, potentially compromising confidentiality and integrity of those accounts' resources.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch is currently documented. Until a fix is available, restrict use of shared tokens to trusted parties and monitor for suspicious use of X-Crabbox-Owner and X-Crabbox-Org headers in requests.
