CVE-2026-74240: Improper Authentication in Red Hat Red Hat OpenShift Update ServiceCVE-2026-74240 0 CVE-2026-74240 is a medium severity vulnerability in Red Hat Quay's JWT validation for federated robot accounts and single sign-on authentication. The flaw involves improper enforcement of audience, 'azp', and 'sub' claims in JWT tokens, allowing an attacker with a valid token from the same identity provider to bypass configured security restrictions. Exploitation requires a pre-existing valid token from the same IdP, limiting the attack surface. The vulnerability affects Red Hat OpenShift Update Service, which is a cloud-hosted service. Red Hat provides configuration-based mitigations to enforce proper claim validation and recommends restarting affected services after applying these changes.
