# LearnPress Course Wishlist: any user's wishlist editable via user_id

Link for people: https://infrastack.ai/live/CVE-2026-127213 (this .md is for agents)

The LearnPress Course Wishlist add-on trusts a user_id parameter instead of the logged-in session, so remote attackers can add or remove courses from any user's wishlist. Attackers can also enumerate user and course IDs to learn which courses a given user has wishlisted.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed LearnPress Course Wishlist add-on version in the WordPress plugins list or plugin directory.
- Confirm whether the `load_content_via_ajax` REST route is reachable on the site.

## Fix

- LearnPress Course Wishlist Add-on: move to `4.1.2` or later.

## Timeline

## From the sources

LearnPress Course Wishlist Add-on before 4.1.2 contains an insecure direct object reference vulnerability that allows remote attackers to manipulate any user's course wishlist by supplying an arbitrary user_id parameter to the render_button callback instead of relying on the session identity. Attackers can exploit the publicly accessible load_content_via_ajax REST route, which only requires a public wp_rest nonce, to add or remove courses from any user's wishlist and determine whether a given course is wishlisted by iterating user_id and course_id values.
