The CM FAQ WordPress plugin suffers from a reflected cross-site scripting vulnerability due to the use of remove_query_arg without appropriate escaping on URL parameters. This flaw allows unauthenticated attackers to inject and execute arbitrary web scripts by tricking users into clicking malicious links. The vulnerability affects all versions up to 1.2.5. It has a CVSS 3.1 base score of 6.1, indicating medium severity. No vendor advisory or patch information is currently available, and the plugin is not a cloud service, so remediation depends on plugin updates from the vendor.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser, potentially resulting in information disclosure or user session manipulation. The vulnerability requires user interaction (clicking a crafted link) and does not require privileges. There is no indication of impact on availability. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution with links related to the CM FAQ plugin and consider disabling or removing the plugin if possible.
