AI Analysis
Technical Summary
Cotonti through version 1.0.0 fails to validate anti-CSRF tokens in the contact plugin submission handler. This vulnerability enables attackers to perform cross-site request forgery (CSRF) attacks by submitting contact forms on behalf of authenticated victims without their consent. The forged messages are sent to the administrator inbox, potentially leading to message spoofing or spam.
Potential Impact
The vulnerability allows attackers to send forged messages attributed to authenticated users to the administrator inbox. While it does not impact confidentiality or availability, it can lead to integrity issues by enabling message forgery. The CVSS score is 4.3 (medium severity), reflecting limited impact primarily on message integrity.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should consider disabling the vulnerable contact plugin or implementing additional CSRF protections at the application or web server level.
