CVE-2026-110284 — LifterLMS <= 10.3.1 - Authenticated (Contributor+) Local File Inclusion via 'lifterlms_checkout' Shortcode Attributes

The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 10.3.1 via attacker-controlled attributes of the [lifterlms_checkout] shortcode. This is due to the llms_get_template() helper performing extract() on the shortcode attribute array before resolving the template path, which allows the attacker-supplied 'template_name' and 'default_path' shortcode attributes to overwrite the function's local parameters and ultimately control the path passed to a PHP include. This makes it possible for authenticated attackers, with Instructor-level access and above, to include and execute arbitrary files on the server, that can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where files with safe extensions containing attacker-controlled content can be uploaded and included.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.7% (30-day exploitation probability)+8
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Lifterlms LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

  • Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
  • Look for parameters with command/query metacharacters and unexpected child processes of the service.
