Published

OpenClaw before 2026.4.29 contains an SSRF policy bypass vulnerability in browser debug and export routes that allows reuse of already-open blocked tabs. Attackers with access to these routes can bypass private-network SSRF policies by reusing blocked tabs to export or inspect content that should remain protected.

### Summary Browser debug/export routes could reuse already-open blocked tabs. In affected versions, a caller that can reference an already-open browser tab could reuse blocked private-network tabs without reapplying the expected SSRF policy. This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed. ### Impact When the affected feature is enabled and reachable, this could export or inspect content from a tab that should have stayed behind the browser network policy. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path. ### Patched Versions The first stable patched version is `2026.4.29`. ### Mitigations close blocked tabs before debug/export use and restrict browser debug routes until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.

Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
