CVE-2026-2263
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Hustle – Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'hustle_module_converted' AJAX action in all versions up to, and including, 7.8.10.2. This makes it possible for unauthenticated attackers to forge conversion tracking events for any Hustle module, including draft modules that are never displayed to users, thereby manipulating marketing analytics and conversion statistics.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Hustle WordPress plugin lacks a capability check on the 'hustle_module_converted' AJAX action, allowing unauthenticated users to forge conversion tracking events. Attackers can manipulate marketing analytics by submitting fake conversion data for any module, including unpublished drafts, due to missing authorization validation on the AJAX endpoint.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Hustle plugin is installedNavigate to WordPress admin > Plugins and verify Hustle (by WPMU DEV) is installed and activeAffected if Hustle plugin is installed and active in WordPress
-
Identify installed Hustle versionGo to Plugins page in WordPress admin, locate Hustle, and record the version number displayedAffected if Version is below 7.8.10.3 (the patched version)
-
Verify AJAX action is exposedMake a request to your site's /wp-admin/admin-ajax.php?action=hustle_module_converted (POST or GET) and observe if it returns a response without requiring authenticationAffected if The AJAX action responds without authentication or returns any data indicating the endpoint is reachable
-
Check if Hustle modules existIn WordPress admin, go to Hustle > All Modules and note whether any modules (popups, embeds, slides, emails) exist, including draftsAffected if Any modules are configured, even unpublished drafts, which could have false conversion data injected
If Hustle is installed with a version below 7.8.10.3 and the hustle_module_converted AJAX endpoint is accessible without authentication, the environment is affected by this broken access control vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the Hustle plugin to version 7.8.10.3 or later, which should include proper capability/authorization checks on the AJAX action. Until then, consider restricting the affected AJAX endpoint at the web server level or disabling the plugin if update is not possible.
