medium

Description

OpenClaw versions prior to 2026.2.2 contain a server-side request forgery vulnerability in attachment and media URL hydration that allows remote attackers to fetch arbitrary HTTP(S) URLs. Attackers who can influence media URLs through model-controlled sendAttachment or auto-reply mechanisms can trigger SSRF to internal resources and exfiltrate fetched response bytes as outbound attachments.
