AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N

Name of the Vulnerable Software and Affected Versions WordPress versions prior to 4.6

Description The issue allows remote authenticated users to bypass intended read-access restrictions. This is related to the wp ajax update plugin function in wp-admin/includes/ajax-actions.php, which makes a get plugin data call before checking the update plugins capability. The plugin parameter to the /wp-admin/admin-ajax.php API endpoint is involved.

Recommendations For versions prior to 4.6, update to version 4.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the wp-admin/admin-ajax.php API endpoint to minimize the risk of exploitation. Avoid using the plugin parameter in the affected API endpoint until the issue is resolved.
