Name of the Vulnerable Software and Affected Versions Gotham Block Extra Light versions prior to 1.5.1

Description The Gotham Block Extra Light plugin for WordPress is susceptible to Stored Cross-Site Scripting through admin settings. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level permissions or higher to inject arbitrary web scripts into pages. These scripts execute when a user accesses the injected page. This issue specifically impacts multi-site installations and those where unfiltered html has been disabled.
