CVE-2026-42206: Roadiz Core-Bundle-Dev-App

Medium severity, CVSS 5.7. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Roadiz Core-Bundle-Dev-App: before 2.3.43 (fixed in 2.3.43); from 2.5.0, before 2.5.45 (fixed in 2.5.45); from 2.6.0, before 2.6.31 (fixed in 2.6.31); from 2.7.0, before 2.7.18 (fixed in 2.7.18)
