CVE-2026-22598Network attack vector

Authenticated denial of service via invalid TimeProfile profile

Published Jan 21, 2026 · Updated Jan 21, 2026

Improper input validation in the ManageIQ API before radjabov-2 allows remote authenticated users to cause request timeouts. The TimeProfile model accepts profile keys, day and hour values, and time-zone names without checking their permitted forms before persistence. A low-privileged API user can store a malformed profile that makes later UI and API requests time out, interrupting the service without reported data disclosure or modification.
