Rt Mega Menu
Monthly
Stored XSS in the RT Mega Menu WordPress plugin (versions before 1.5.2) allows any subscriber-level authenticated user to inject persistent JavaScript into the site's public navigation, executing against every visitor who hovers over menu items - including administrators - enabling session theft and full site takeover. The AJAX endpoint that saves mega-menu configuration performs no capability check, relying solely on a nonce that any logged-in user can read from a standard admin page, making the access barrier trivially low. A public exploit is documented by WPScan, and the vendor has released version 1.5.2 as the confirmed fix; no public exploit identified at time of analysis corresponds to active widespread exploitation (no CISA KEV listing), though the public exploit code exists and the low subscriber-level barrier makes this dangerous on sites with open registration.
