CVSS 8.8 High EPSS 24.4% · p98 Patch this week
Should you act?
High exploit likelihood
EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 24.4%, percentile 98: FIRST’s model estimates a 24.4% chance of exploitation activity in the next 30 days, higher than 98% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Editorial verdict: Patch this week. OpenClaw CVE-2026-25253: One-Click RCE via Token Leak — Fixed since January, but any OpenClaw install that missed updates can be taken over by its owner clicking one link, and a loopback-only setup does not save it.
