CERTFR-2026-AVI-1078
Vulnerability from certfr_avis - Published: 2026-08-25 - Updated: 2026-08-25
De multiples vulnérabilités ont été découvertes dans Keycloak. Elles permettent à un attaquant de provoquer un contournement de la politique de sécurité et un problème de sécurité non spécifié par l'éditeur.
Le CERT-FR a connaissance d'une preuve de concept publique pour la vulnérabilité CVE-2026-18963 qui permet à un attaquant non authentifié de prendre le contrôle d'un compte dont il connait l'identifiant.
Mesure de contournement
Si l'application de la mise à jour n'est pas possible, l'équipe de sécurité de Red Hat recommande de désactiver la fonctionnalité "Forgot password" pour tous les domaines d'authentification (cf. section Documentation). Celle-ci n'est pas activée par défaut.
Solutions
Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

The mechanism used to protect the account-linking process from unauthorized requests relies on a hash that can be predicted by a malicious OIDC client. By tricking a user into authenticating, an attacker-controlled client can forge a valid linking URL to connect the victim\u0027s account to an attacker\u0027s external identity. This results in a full account takeover, allowing the attacker to log in as the victim."
