What is CVE-2026-35629?

OpenClaw versions prior to 2026.3.25 are susceptible to a server-side request forgery issue due to inadequate protections on configured base URLs within multiple channel extensions. This vulnerability allows attackers to exploit unguarded fetch() calls targeting configured endpoints, which could enable them to redirect requests to internal systems that are typically secured against external access, thereby exposing restricted resources.
