The FluentCRM plugin for WordPress suffers from a stored XSS vulnerability due to improper neutralization of input in the 'fluentcrm_content' shortcode. This allows authenticated users with contributor or higher privileges to inject arbitrary web scripts that execute in the context of other users viewing the injected content. The vulnerability affects all versions up to and including 2.9.84. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges, no user interaction, and impacts confidentiality and integrity with no availability impact.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages rendered by the plugin. This can lead to unauthorized actions performed in the context of other users, potentially compromising user data confidentiality and integrity. There is no direct impact on system availability. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access and above to trusted users only. Monitor for plugin updates from the vendor and apply official patches promptly once released.
