CVE ID :CVE-2026-96446
Published : Sept. 23, 2026, 12:17 p.m. | 53 minutes ago
Description :A flaw was found in the Pushed Authorization Request PAR implementation of Keycloak. The issue occurs when the silent authentication path prompt=none is used, which allows the authorization process to skip certain steps if a user is already logged in. Due to this bypass, the security rule that ensures a pushed request URI is used only once is not enforced. An attacker could potentially reuse a request URI to obtain multiple authorization codes for a user who is already signed in, violating security standards like FAPI-2.
Severity: 4.2 | MEDIUM
