At a glance

CVE-2025-6993 is a high-severity Missing Authorization vulnerability in the Ultimate WP Mail WordPress plugin, affecting versions 1.0.17 – 1.3.6. It carries a CVSS score of 7.5 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.3.7; sites on affected versions should update now. Disclosed July 2025, reported by kr0d.

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-862: Missing Authorization

Ultimate WP Mail 1.0.17 – 1.3.6 carries this weakness at edit_posts, and reaching it takes an account at Contributor level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Ultimate WP Mail the fix is 1.3.7: builds 1.0.17 – 1.3.6 are affected, anything from 1.3.7 onward is not.

Remediation

Update to version 1.3.7, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Ultimate WP Mail 1.3.7 closes this, and updating the plugin is the step that ends it.
