Machine-written summary

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

Keycloak (org.keycloak:keycloak-services, Maven) versions before 26.0.13 and from 26.2.0 before 26.2.6 are affected. An attacker with a registered account can start an identity-provider first login flow that merges accounts, then change their email address to a victim's address so that a verification email is sent to the victim. If the victim clicks the link, the attacker can gain access to the victim's account. Upgrade to 26.0.13 or 26.2.6.
