The Ultimate WP Mail plugin for WordPress is vulnerable to Privilege Escalation due to improper authorization within the get_email_log_details() AJAX handler in versions 1.0.17 to 1.3.6. The handler reads the client-supplied post_id and retrieves the corresponding email log post content (including the password-reset link), relying only on the ‘edit_posts’ capability without restricting to administrators or validating ownership. This makes it possible for authenticated attackers, with Contributor-level access and above, to harvest an admin’s reset link and elevate their privileges to administrator.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.

Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource, based on the user’s privileges and any permissions or other access-control specifications that apply to the resource. When access control checks are not applied, users are able to access data or perform actions that they should not be allowed to perform. This can lead to a wide range of problems, including information exposures, denial of service, and arbitrary code execution.
