Title
Aap-controller: aap-gateway: account hijacking and unauthorized access via unverified email linking
Summary
A flaw was found in the AAP gateway. The user auto-link strategy, introduced in AAP 2.6, automatically links an external Identity Provider (IDP) identity to an existing AAP user account based on email matching without verifying email ownership. This allows a remote attacker to potentially hijack a victim's account or gain unauthorized access to other accounts, including administrative accounts, by manipulating the IDP-provided email.

CVE-2026-9798 (GCVE-0-2026-9798)
Vulnerability from cvelistv5 – Published: 2026-05-28 04:37 – Updated: 2026-05-29 18:30

Title
Keycloak: keycloak: brute-force protection bypass in ciba flow
Summary
A flaw was found in Keycloak, an open-source identity and access management solution. When a user account is temporarily locked due to repeated failed login attempts, an attacker with valid client credentials can exploit the Client-Initiated Backchannel Authentication (CIBA) flow to bypass this brute-force protection. This allows continued authentication attempts and token issuance even when the account should be locked, potentially enabling further unauthorized access attempts.
