Machine-written summary

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

keycloak-services versions 26.3.0 to before 26.4.1, and versions before 26.2.11, keep existing sessions alive after the Remember Me realm setting is disabled, until they expire. This widens the window for session hijacking or long-term unauthorized access. The source gives few details on attacker prerequisites. Upgrade to 26.4.1 or 26.2.11.
