The 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, 1.42.1. 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 author-level access and above, to dismiss, ignore, or restore accessibility audit issue records belonging to posts they are not permitted to edit by supplying an issue from their own post as an authorization token to affect matching issues across the entire site. An Author-level user can exploit this by passing largeBatch=true on a dismiss-issue request referencing one of their own post's issues, causing the handler to bulk-modify all site-wide accessibility issues sharing the same 'object' value - including those belonging to administrator-owned posts.
AnalysisAI
Authorization bypass in Equalize Digital Accessibility Checker for WordPress (all versions ≤ 1.42.1) allows authenticated author-level users to dismiss, ignore, or restore accessibility audit records belonging to posts they do not own. The flaw lies in the plugin's REST API handler accepting the attacker's own issue ID as a sufficient authorization token, and the largeBatch=true parameter then triggers a bulk operation that propagates the action across all site-wide issues sharing the same 'object' value - including those on administrator-owned posts. No public exploit identified at time of analysis, and this CVE is not listed in CISA KEV; however, the Wordfence advisory includes direct source code references confirming the vulnerable logic.
Technical ContextAI
The vulnerability is classified as CWE-862 (Missing Authorization) and exists within the REST API class of the plugin (includes/classes/class-rest-api.php). Wordfence references three specific lines in this handler (L349, L1232, and L1247) across confirmed affected versions 1.39.0 and 1.42.0. The root cause is that the authorization check validates whether the supplied issue ID belongs to a post the requesting user can edit, but then allows the largeBatch=true flag to extend the operation to all issues sharing the same 'object' value site-wide - without re-validating ownership for those additional records. This is an object-level authorization failure: the token grants access to the user's own resource but is incorrectly used to authorize cross-resource batch operations. Affected CPE: cpe:2.3:a:equalizedigital:equalize_digital_accessibility_checker_-_wcag,_ada,_eaa_and_section_508_compliance:*:*:*:*:*:*:*:*.
RemediationAI
Update the Equalize Digital Accessibility Checker plugin to a version beyond 1.42.1. A fix is available via upstream commit in the plugin's Trac repository (changeset 3553926 at https://plugins.trac.wordpress.org/changeset?reponame=&old=3553926%40accessibility-checker&new=3553926%40accessibility-checker); however, the specific patched release version number is not independently confirmed in the available data - verify the latest available version in the WordPress Plugin Directory before updating. If an immediate update cannot be applied, restrict the granting of author-level and above roles to fully trusted users only, which removes the required privilege prerequisite. Alternatively, a web application firewall rule blocking REST API requests containing largeBatch=true to the dismiss-issue endpoint would neutralize the bulk-operation attack path, though this may degrade the plugin's legitimate batch audit management functionality. No generic network-level block is effective given the legitimate REST API usage pattern.
