{"id":"CVE-2026-42206","aliases":["GHSA-3gx8-q682-38mx"],"url":"https://o3.security/vulnerability/CVE-2026-42206","summary":"Roadiz OpenID Connect nonce generated but never validated — ID token replay attack","details":"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.","published":"2026-05-08T21:54:32.715Z","modified":"2026-08-12T03:51:10.308755336Z","cvss":null,"epss":{"score":0.00152,"percentile":0.04914,"asOf":"2026-08-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"roadiz/openid","fixedVersion":"2.7.18"},{"ecosystem":"Packagist","name":"roadiz/openid","fixedVersion":"2.6.31"},{"ecosystem":"Packagist","name":"roadiz/openid","fixedVersion":"2.5.45"},{"ecosystem":"Packagist","name":"roadiz/openid","fixedVersion":"2.3.43"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42206.json"},{"type":"ADVISORY","url":"https://github.com/roadiz/core-bundle-dev-app/security/advisories/GHSA-3gx8-q682-38mx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42206"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:10.308755336Z"}}
