MEDIUM5.3EPSS 0.04%Keycloak: Replay of action tokens via improper handling of single-use entries
發布日:2026/4/2修改日:2026/4/4
描述
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.
