CVE-2026-117627

5.4 medium Published
NVD · CVE.org

A flaw was found in the JWT Authorization Grant implementation of the keycloak-services component. When an OIDC or Google identity provider is configured with specific login restrictions, such as claim filtering, these checks are correctly applied during standard browser logins but are skipped during the JWT-based grant flow. This allows an authenticated client to obtain access tokens for a user even if their identity provider claims should have blocked the login.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
