CVE-2026-11355

DT LMS <= 1.1 - Missing Authorization to Unauthenticated Arbitrary Plugin Settings Modification via Multiple AJAX Actions

Published Sep 12, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
The DT LMS – elearning, WordPress LMS plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on multiple AJAX handlers (including dtlms_save_poc_settings, dtlms_save_skin_settings, and dtlms_save_options_settings) in versions up to, and including, 1.1. These handlers are registered on the wp_ajax_nopriv_* hook and contain no capability check, no nonce verification, and pass user-supplied data directly to update_option(). This makes it possible for unauthenticated attackers to overwrite arbitrary plugin option values stored in the wp_options table, including Point-of-Contact email configuration and skin/branding settings, which can be used to alter the appearance and behavior of the LMS for all site visitors.

Analysis

AI-generated

Technical impact

The DT LMS – elearning plugin allows unauthenticated users to send AJAX requests that are handled by functions that omit capability checks, nonce verification, and pass user‑supplied data directly to update_option(). This flaw lets an attacker overwrite any plugin setting stored in the wp_options table, such as contact emails, branding images, or skin choices. The attacker can therefore alter the appearance and communication behavior of the LMS for all visitors without logging in.

Affected Systems

The vendor is DesignThemes and the product is the DT LMS – elearning WordPress LMS Plugin. Versions up to and including 1.1 are vulnerable. WordPress sites that have this plugin installed at those versions are affected. No newer plugin versions are reported to be vulnerable.

Risk and Exploitability

The CVSS score of 5 severity range, while the EPSS score of less than 1% indicates a low probability of widespread exploitation at present. The vulnerability is not listed in the C vector is unauthenticated and requires no user privilege, an attacker only needs to send crafted HTTP requests to the vulnerable AJAX endpoints to experience the impact for all site visitors.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade the DT LMS – elearning plugin to any version newer than 1.1 that includes capability checks for the affected AJAX actions.
  • If an upgrade is not feasible, disable or block the wp_ajax_nopriv_* handlers that lack authorization checks by modifying the plugin code or using a security plugin to restrict unauthenticated AJAX calls.
  • Continuously monitor the wp_options table for unexpected changes to plugin options and review server logs for suspicious AJAX requests.
