Themify Builder Stored XSS Vulnerabilities

Stored Cross-Site Scripting in the Themify Builder WordPress plugin (all versions through 7.7.6) enables authenticated attackers holding contributor-level access or higher to persist arbitrary JavaScript via the Map Module's `b_width_map` field. Because the scope changes (S:C in CVSS), the injected payload executes inside every subsequent visitor's browser context - enabling session hijacking, credential theft, or administrative account takeover against any user who views an affected page. No public exploit code has been identified and this vulnerability is not listed in CISA KEV, but the low exploitation complexity and network-accessible attack surface make it a meaningful risk on sites with open or broad contributor registration.

Stored XSS in the Themify Builder WordPress plugin (all versions through 7.7.6) allows contributor-level authenticated users to inject persistent JavaScript via the 'height_slider' Slider Module field, which executes in the browser of any visitor who loads an injected page. The scope change (S:C in CVSS) captures the cross-context impact: attacker payload runs in victims' sessions, enabling session hijacking, credential theft, or unauthorized admin actions. No active exploitation is confirmed in CISA KEV, but a patch commit (changeset 3601964) is visible in the WordPress plugin SVN repository, suggesting a fix has been committed beyond version 7.7.6.
