This issue occurs due to improperly enforcing token types when validating signatures locally.

LOW 3.4EPSS 0.29%

Does this matter?

Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.

Description

A flaw was found in Keycloak. This issue occurs due to improperly enforcing token types when validating signatures locally. This could allow an authenticated attacker to exchange a logout token for an access token and possibly gain access to data outside of enforced permissions.
