Stored Cross-Site Scripting in the Fluent Support WordPress plugin (all versions through 2.3.0) allows authenticated contributors to inject persistent JavaScript via the 'redirect-to' shortcode attribute due to missing input sanitization and output escaping in AuthHandler.php. The injected payload executes in the browser context of any user who subsequently visits the affected page, enabling session hijacking, credential theft, or administrative action forgery. Practical exploitation is significantly constrained: the payload resides in a hidden HTML attribute and only triggers in certain browsers when the victim activates specific keyboard access keys, making mass exploitation unlikely despite the network-accessible attack path. No public exploit code has been identified and this CVE is not listed in the CISA KEV catalog.
