Name of the Vulnerable Software and Affected Versions Free MailClient FMC versions n/a through 1.0

Description The issue is related to a Cross-Site Request Forgery (CSRF) vulnerability that also allows Stored XSS. This means an attacker could potentially trick a user into performing unintended actions on the web application, and also store malicious scripts that could be executed by other users.

Recommendations For versions n/a through 1.0, update to a version that fixes the CSRF vulnerability, ensuring that the update also addresses the Stored XSS issue. As a temporary workaround, consider disabling any features that may be exploited through CSRF attacks until a patch is available. Restrict access to sensitive areas of the Free MailClient FMC to minimize the risk of exploitation.
