CVE-2026-62226 Overview
CVE-2026-62226 is an authorization bypass vulnerability affecting OpenClaw versions 2026.3.28 through versions prior to 2026.5.19. The flaw resides in the browser act route, which fails to properly validate current-tab URL checks before executing privileged actions. Attackers with lower-trust access, or those able to influence configured input paths, can invoke functionality that should require stronger authorization or policy enforcement. The issue is classified under CWE-918: Server-Side Request Forgery (SSRF), reflecting the ability to coerce the server into acting on attacker-influenced URLs.
Critical Impact
Authenticated low-privilege actors can bypass authorization checks in the browser act route and trigger actions requiring stronger policy validation.
Affected Products
- OpenClaw 2026.3.28 and later versions before 2026.5.19
- Node.js-based deployments of OpenClaw as identified in the CPE cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:node.js:*:*
- Any downstream integrations relying on the browser act route for URL-scoped authorization

Technical Details for CVE-2026-62226
Vulnerability Analysis
OpenClaw exposes a browser act route that performs actions gated by the URL of the current tab. The route trusts URL data supplied through the request flow without applying strict validation against the authorization policy expected for privileged actions. As a result, callers who should be constrained by policy checks can drive the route to execute functionality reserved for higher-trust contexts. The behavior aligns with SSRF-adjacent authorization weaknesses, where attacker-controlled URL context influences server-side decisions and downstream operations.
Root Cause
The root cause is missing or incorrect validation of the current-tab URL used to authorize actions in the browser act route. The route treats the URL as an authoritative indicator of caller context, but the check can be satisfied by lower-trust inputs. Because policy enforcement is coupled to an unverified value, the trust boundary between low-privilege callers and privileged operations collapses.
Attack Vector
Exploitation occurs over the network and requires low privileges with no user interaction. An attacker with authenticated access, or one able to influence configured input paths that reach the browser act route, submits crafted URL values that satisfy the flawed check. The server then processes the request as if it originated from an authorized context. Successful abuse impacts the confidentiality of subsequent systems the route can reach, consistent with the SSRF classification.
No verified public proof-of-concept code is available. Refer to the VulnCheck Advisory: OpenClaw Bypass and the GitHub Security Advisory GHSA-x863-pqjw-hmgf for technical details.
Detection Methods for CVE-2026-62226
Indicators of Compromise
- Requests to the browser act route containing crafted or unexpected current-tab URL parameters that do not match legitimate client navigation patterns.
- Successful privileged actions logged with originating sessions that lack the corresponding authorization scope.
- Outbound connections initiated by OpenClaw to hosts outside the expected policy allowlist.
Detection Strategies
- Correlate authentication context with actions executed through the browser act route to identify privilege mismatches.
- Baseline legitimate URL values passed to the route and alert on deviations, malformed schemes, or internal-only targets.
- Inspect application logs for repeated route invocations that precede successful state changes from low-trust accounts.
Monitoring Recommendations
- Enable verbose request logging on the browser act route, capturing user identity, URL parameter, and authorization decision.
- Monitor egress traffic from OpenClaw hosts for unexpected internal destinations indicative of SSRF-style abuse.
- Track versions across OpenClaw deployments and alert when instances running 2026.3.28 through pre-2026.5.19 builds are detected.
How to Mitigate CVE-2026-62226
Immediate Actions Required
- Upgrade OpenClaw to version 2026.5.19 or later, which contains the fix for the browser act route authorization check.
- Audit accounts with access to the browser act route and revoke unused low-trust credentials that could reach the endpoint.
- Review historical logs for prior invocations of the route with anomalous URL parameters and validate that no privileged actions were performed out of policy.
Patch Information
The maintainers released a fix in OpenClaw 2026.5.19. See the GitHub Security Advisory GHSA-x863-pqjw-hmgf for the vendor advisory and remediation guidance.
Workarounds
- Restrict network exposure of the browser act route to trusted internal callers using a reverse proxy or firewall policy.
- Enforce an allowlist of URL schemes and hosts accepted by the route until the patched version is deployed.
- Require additional out-of-band authorization for privileged actions triggered through the route where feasible.
