CVE-2026-125652

medium

Description

A flaw was found in the keycloak-services component of Keycloak, which provides the core authentication and authorization logic for the identity provider. The issue occurs when a user initiates a login after visiting the password reset page, causing the system to skip mandatory security checks for Proof Key for Code Exchange (PKCE). This could allow an attacker who intercepts a login code to gain unauthorized access to the user's account without needing the required security verifier.
