The frenchsquared Comment-Emailer plugin versions up to 1.0.5 contain a CSRF vulnerability that enables stored XSS attacks. This means an attacker can trick a user into submitting a crafted request that results in malicious script being stored and executed in the context of the affected application. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low confidentiality, integrity, and availability impacts.

Successful exploitation could allow an attacker to execute stored XSS attacks via CSRF, potentially leading to unauthorized actions and compromise of user data or session integrity. The impact includes partial loss of confidentiality, integrity, and availability of the affected system. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, users should consider implementing CSRF protections such as verifying anti-CSRF tokens and restricting actions to authenticated users. Monitor official vendor channels for updates and apply patches promptly once released.
