Machine-written summary

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

Keycloak (org.keycloak:keycloak-core) versions before 24.0.7 and from 25.0.0 before 25.0.4 accept expired one-time passcodes when FreeOTP is used with the default 30-second token period. Such codes remain valid for about 60 seconds instead of 30, so two codes are valid at once, which widens the window for account compromise. Upgrade to version 24.0.7 or 25.0.4.
