CVE-2025-59361: Chaos Controller Manager is vulnerable to OS command injection
The cleanIptables mutation in Chaos Controller Manager is vulnerable to OS command injection.
CVSS 9.8 Critical EPSS 3.3% · p88
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. 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 3.3%, percentile 88: FIRST’s model estimates a 3.3% chance of exploitation activity in the next 30 days, higher than 88% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes
github.com/chaos-mesh/chaos-mesh(Go) < 2.7.3, fixed in 2.7.3. Check your lockfile, including transitive dependencies.
