EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.6 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 67% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
