CVE-2026-53832Public exploit

Operator impersonation via trusted-proxy header forgery

Published Jun 12, 2026 · Updated Jun 12, 2026

Authentication bypass in OpenClaw before 2026.5.18 allows local users to assume an operator identity through forged proxy headers. The Gateway's trusted-proxy path accepts identity headers from same-host callers that reach the proxy-facing port instead of requiring the designated proxy to supply them. The feature must be enabled and reachable from a lower-trust local process; resulting operator authority depends on configured permissions and tools.
