CVE-2026-42206 – Roadiz OpenID Connect nonce generated but never validated — ID token replay attack

CVE ID :CVE-2026-42206

Published : May 8, 2026, 9:54 p.m. | 31 minutes ago

Description :Roadiz is a polymorphic content management system based on a node system. Prior to versions 2.3.43, 2.5.45, 2.6.31, and 2.7.18, the roadiz/openid package generates an OIDC nonce in OAuth2LinkGenerator::generate() and includes it in the authorization request sent to the identity provider, but never stores it and never validates it on the callback. The OpenIdJwtConfigurationFactory validation chain does not include a nonce constraint, and OpenIdAuthenticator::authenticate() never checks the nonce claim in the returned ID token against a stored value. This issue has been patched in versions 2.3.43, 2.5.45, 2.6.31, and 2.7.18.

Severity: 0.0 | NA
