CVE-2026-28467Public exploitNetwork attack vector

Internal resource disclosure via unguarded media fetches

Published Mar 5, 2026 · Updated Mar 5, 2026

SSRF in OpenClaw before 2026.2.2 allows remote attackers to read internal HTTP(S) resources through crafted attachment media URLs. The attachment and media hydration paths passed attacker-influenced URLs to raw fetch operations without private-address, DNS-pinning, or redirect checks. Exploitation requires control of a media URL through sendAttachment or an auto-reply path and returns reachable internal response bytes as an outbound attachment, without granting code execution.
