CVE-2026-105949
HIGH 8.8Cruise 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.
Severe if exploited (CVSS 8.8), but no known exploitation and low modeled probability. Patch on a normal cadence.
