Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Keycloak-services versions below 24.0.9, and versions from 25.0.0 up to but not including 26.0.6, are vulnerable to inefficient regular expression complexity. If untrusted data is passed to the SearchQueryUtils method, an attacker can cause a denial of service by exhausting system resources. Upgrade to version 24.0.9 or 26.0.6, depending on your release line.
