DescriptionThe Equalize Digital Accessibility Checker – WCAG, ADA, EAA and Section 508 compliance plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.42.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify the ignore state, ignore reason, and ignore comment of arbitrary accessibility issues across the entire site — including mass modification of all rows sharing an 'object' identifier when largeBatch=true is supplied — corrupting accessibility audit integrity by hiding or dismissing findings outside their authorization scope.
