What happened

Cruise Control's Jetty ConstraintSecurityHandler registers security constraints on exact path specs without a catch-all wildcard constraint and without calling setDenyUncoveredHttpMethods(true). The servlet routes requests using Path.of(pathInfo).getFileName(), which strips all leading segments and trailing slashes.

Requests like POST /kafkacruisecontrol/x/rebalance bypass authentication entirely but still dispatch to admin endpoints. All 15 admin endpoints become reachable without authentication. In AMQ Streams, the Strimzi operator's NetworkPolicy restricts Cruise Control port 9090 to operator pods only, reducing effective severity to Important.

About this data

This record was ingested from a data source. Retrieved: Oct 26, 2026, 19:40 UTC. Ingestion is not an independent editorial investigation.

NVD status: Awaiting Analysis. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
