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.\n\n### Details\nIn `src/OAuth2LinkGenerator.php`, a nonce is created and sent to the IdP:\n```php\n'nonce' => $this->tokenGenerator->generateToken(),\n```\nHowever, this value is neither stored in session, cache, nor any other persistent store.\n\nIn `src/OpenIdJwtConfigurationFactory.php`, the JWT validation constraints are:\n- `LooseValidAt` (expiry)\n- `PermittedFor` (audience)\n- `IssuedBy` (issuer)\n- `HostedDomain` (optional)\n- `UserInfoEndpoint` (optional)\n\n**No nonce constraint is present.**\n\nIn `src/Authentication/OpenIdAuthenticator.php`, the `authenticate()` method validates the state CSRF token correctly (fixed in v2.7.10), but never retrieves a stored nonce or compares it against the `nonce` claim in the ID token.\n\n### PoC\n1. Obtain a valid ID token from a legitimate OIDC flow for a target user (e.g. via network interception, browser history leak, or referrer header exposure on a non-HTTPS redirect).\n2. Replay the ID token: Since the nonce in the token is never cross-checked against a client-stored value, the token passes all validation constraints as long as it has not expired.\n3. Result: An attacker can authenticate as the victim within the ID token's validity window.\n\nAdditionally, in an authorization code flow with multiple concurrent sessions, a malicious IdP or a compromised token endpoint could inject a token with a mismatched nonce, and the application would accept it silently.\n\n### Impact\n- **ID token replay attacks**: Valid but intercepted tokens can be reused for authentication within their validity period.\n- **Token injection attacks**: A malicious or compromised identity provider can inject tokens across sessions without detection.\n- Affects any Roadiz application using the `roadiz/openid` package with OpenID Connect SSO.\n\nThe OIDC Core 1.0 specification (Section 3.1.3.7) explicitly requires clients to verify the `nonce` claim if it was present in the authorization request.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2026-42206", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.00021", "scoring_system": "epss", "scoring_elements": "0.06115", "published_at": "2026-06-06T12:55:00Z" }, { "value": "0.00021", "scoring_system": "epss", "scoring_elements": "0.06064", "published_at": "2026-06-08T12:55:00Z" }, { "value": "0.00021", "scoring_system": "epss", "scoring_elements": "0.06111", "published_at": "2026-06-07T12:55:00Z" }, { "value": "0.00021", "scoring_system": "epss", "scoring_elements": "0.06127", "published_at": "2026-06-05T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2026-42206" }, { "reference_url": "https://github.com/roadiz/core-bundle-dev-app", "reference_id": "", "reference_type": "", "scores": [ { "value": "5.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:P" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/roadiz/core-bundle-dev-app" }, { "reference_url": "https://github.com/roadiz/core-bundle-dev-app/security/advisories/GHSA-3gx8-q682-38mx", "reference_id": "", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" }, { "value": "5.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:P" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-13T17:19:35Z/" } ], "url": "https://github.com/roadiz/core-bundle-dev-app/security/advisories/GHSA-3gx8-q682-38mx" }, { "reference_url": "https://nvd.nist.gov/vuln/detail/CVE-2026-42206", "reference_id": "", "reference_type": "", "scores": [ { "value": "5.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:P" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-42206" }, { "reference_url": "https://github.com/advisories/GHSA-3gx8-q682-38mx", "reference_id": "GHSA-3gx8-q682-38mx", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-3gx8-q682-38mx" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/111022?format=api", "purl": "pkg:composer/roadiz/openid@2.3.43", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:composer/roadiz/openid@2.3.43" }, { "url": "http://public2.vulnerablecode.io/api/packages/111020?format=api", "purl": "pkg:composer/roadiz/openid@2.5.45", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:composer/roadiz/openid@2.5.45" }, { "url": "http://public2.vulnerablecode.io/api/packages/111019?format=api", "purl": "pkg:composer/roadiz/openid@2.6.31", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:composer/roadiz/openid@2.6.31" }, { "url": "http://public2.vulnerablecode.io/api/packages/111017?format=api", "purl": "pkg:composer/roadiz/openid@2.7.18", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:composer/roadiz/openid@2.7.18" } ], "aliases": [ "CVE-2026-42206", "GHSA-3gx8-q682-38mx" ], "risk_score": 3.1, "exploitability": "0.5", "weighted_severity": "6.2", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-8q48-sp2f-ukge" } ], "fixing_vulnerabilities": [], "risk_score": "3.1", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:composer/roadiz/openid@2.3.14" }
