CVE-2025-2779

Insert Headers and Footers Code – HT Script <= 1.1.2 - Missing Authorization to Authenticated (Subscriber+) Limited Options Update

View on CVE.org

Published Apr 2, 2025 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed

Description

The Insert Headers and Footers Code – HT Script plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax_dismiss function in all versions up to, and including, 1.1.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update option values to 1/true on the WordPress site. This can be leveraged to update an option that would create an error on the site and deny access to legitimate users or be used to set some values to true, such as registration.

Analysis

Technical impact

The Insert Headers and Footers Code – HT Script plugin for WordPress is vulnerable because the ajax_dismiss AJAX handler lacks a capability check, allowing an authenticated user with Subscriber-level access or higher to set plugin option values to true. This flaw can be used to trigger errors that deny legitimate users access or to enable features such as registration, thereby disrupting site function or altering configuration state.

Affected Systems

All versions of the WordPress plugin Insert Headers and Footers Code – HT Script up to and including 1.1.2 are affected.

Risk and Exploitability

The CVSS score of 6.5 indicates medium severity, while the EPSS score of less than 1% reflects low likelihood of exploitation. The vulnerability is not listed in CISA KEV. Exploitation requires an authenticated WordPress session and targeting the plugin’s AJAX endpoint; an attacker cannot obtain higher system privileges beyond the existing role.
