Description

OpenClaw before 2026.3.25 contains a server-side request forgery vulnerability in multiple channel extensions that fail to properly guard configured base URLs against SSRF attacks. Attackers can exploit unprotected fetch() calls against configured endpoints to rebind requests to blocked internal destinations and access restricted resources.
