Lifecycle Timeline
2DescriptionCVE.org
Rodauth before 2.47.0 contains a cross-site request forgery protection bypass vulnerability in the JSON request content type validation. Attackers can craft cross-origin form posts with content types containing application/json substrings to bypass CSRF token validation and force victims to authenticate to attacker-controlled accounts.
AnalysisAI
CSRF protection bypass in Rodauth before 2.47.0 allows remote attackers to force victims into authenticated sessions under attacker-controlled accounts by exploiting an unanchored regular expression in the JSON feature. The JSON content type detection regex used a word-boundary anchor instead of a start-of-string anchor, enabling cross-origin form submissions with content types such as 'application/x-www-form-urlencoded; application/json' to be misclassified as JSON requests, which Rodauth treats as CSRF-exempt. …

Vulnerability AssessmentAI
| Exploitation | The target application must have Rodauth's JSON feature explicitly enabled in its Rodauth configuration block (i.e., `:json` included in the `enable` list). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 4.9 with vector AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N is broadly consistent with the vulnerability's mechanics. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Rodauth 2.47.0 or later, which anchors the JSON content type detection regex with `\A` to prevent substring matching attacks; the patching commit is at https://github.com/jeremyevans/rodauth/commit/3e0d7ab2d49a5733d1afcaaf1062b8a8258aa57a and the advisory is at https://github.com/jeremyevans/rodauth/security/advisories/GHSA-hh2f-xw94-5p79. … Detailed patch versions, workarounds, and compensating controls in full report. |
