Should you act?

Normal patch cycle

No exploitation signal; fix it in your next routine update if you are affected. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
  • EPSS 0.5%, percentile 43: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 43% of all scored CVEs (low). EPSS is a probability, not a verdict.
  • Needs an account (low (any account)). Exposure depends on who can log in.
  • Only applies if your dependency tree includes openclaw (npm) <= 2026.3.24, no fixed version listed. Check your lockfile, including transitive dependencies.

What it is

OpenClaw before 2026.3.25 contains a privilege escalation vulnerability allowing non-admin operators to self-request broader scopes during backend reconnect. Attackers can bypass pairing requirements to reconnect as operator.admin, gaining unauthorized administrative privileges.
