OpenClaw before 2026.8.1 SSRF via Browser Wait Predicates

Type: advisorySources: OSV

OpenClaw versions before 2026.8.1 contain a server-side request forgery vulnerability in browser wait predicates that allows attackers to bypass SSRF protections by reaching blocked destinations. Attackers can use the wait --fn function against an existing browser session to request loopback or private destinations without navigation checks applied to other browser actions.
