Machine-written summary

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

Keycloak's org.keycloak:keycloak-services package is affected in versions before 26.5.7. The source describes a flaw in the single-use object store that lets an attacker delete arbitrary single-use entries, which can allow replay of consumed action tokens such as password reset links, potentially leading to account compromise. The source does not say what access an attacker needs. Upgrade to version 26.5.7.
