Subscriber Cross Site Scripting (XSS) in ThemeREX Addons < 2.45.0 versions.
AnalysisAI
Cross-site scripting in ThemeREX Addons (the trx_addons WordPress plugin) below version 2.45.0 lets an authenticated attacker with only a Subscriber-level account inject script content that executes in the browser of any higher-privileged user who views it, enabling session theft or actions performed in the victim's context. Reaching the vulnerable input requires a Subscriber account - trivially obtainable when open WordPress registration is enabled - and successful exploitation is further gated by victim interaction, so an unauthenticated remote attacker cannot exploit a hardened site with registration disabled. …
