Duplicate Advisory: OpenClaw: Same-host trusted-proxy deployments could accept local forged identity headers
Description
OpenClaw versions before 2026.5.18 contain a vulnerability in identity header validation that allows local same-host callers to forge trusted-proxy identity headers. This flaw enables attackers with access to the proxy-facing Gateway port to impersonate operator identities and potentially escalate privileges. The vulnerability has a high severity rating and a CVSS score of 7.7. A patch is available to address this issue.

Technical Analysis
OpenClaw prior to version 2026.5.18 has an identity header validation vulnerability (CWE-290) that permits local same-host attackers to forge trusted-proxy identity headers. This allows an attacker with access to the proxy-facing Gateway port to supply forged identity headers, assume operator identity, and potentially escalate privileges. The vulnerability has a CVSS 3.1 base score of 7.7 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating local attack vector with low complexity and no privileges required, resulting in high confidentiality and integrity impact. The issue is patched in version 2026.5.18.
Potential Impact
An attacker with local access to the proxy-facing Gateway port can forge identity headers to impersonate operator identities, potentially leading to privilege escalation. This compromises confidentiality and integrity of the system but does not affect availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
A patch is available in OpenClaw version 2026.5.18 that fixes this identity header validation vulnerability. Users should upgrade to version 2026.5.18 or later to remediate this issue.
