Keycloak: Replay of action tokens via improper handling of single-use entries
Quick fix
GHSA-rx66-hj7g-28h7 — org.keycloak:keycloak-services: upgrade to the fixed version with the command below.
# pom.xml: bump <version>26.5.7</version> for org.keycloak:keycloak-servicesDetails
A flaw was found in Keycloak. The SingleUseObjectProvider, a global key-value store, lacks proper type and namespace isolation. This vulnerability allows an attacker to delete arbitrary single-use entries, which can enable the replay of consumed action tokens, such as password reset links. This could lead to unauthorized access or account compromise.
