CVE-2026-100576 · Severity: medium · CVSS 5.4 · Published 2026-09-26

OpenClaw is a browser automation platform used by operators to control web sessions programmatically. The vulnerability allows attackers with lower-privilege access to trick an already-open browser into making requests to internal networks or localhost addresses that the application normally blocks, potentially exposing sensitive internal services. An attacker can exploit this by using the wait function with custom predicates to bypass SSRF protections and reach otherwise inaccessible destinations.

## Technical details

The vulnerability exists in OpenClaw's browser wait predicates (wait --fn function) which do not apply the same navigation-level SSRF checks that protect other browser actions. An attacker with network access and low privileges can steer a browser-enabled agent to request loopback or private destinations. The attack requires an existing browser session and lower-trust input control; the fix is available in version 2026.8.1.
