# GLPI: authenticated users can expose restricted knowledge base items and feeds

GLPI is an asset and IT management application. Any logged-in user can send a crafted request that changes the visibility of knowledge base items, reminders, or RSS feeds, letting them read content meant to stay restricted.

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

## How to check

- Check the installed GLPI version in the admin footer or `config/config_db.php`'s parent release, and compare against `10.0.27` and `11.0.9`
- Versions from 0.83 up to but not including `10.0.27`, and from `11.0.0` up to but not including `11.0.9`, are in the affected range

## Fix

- GLPI 10.x: move to `10.0.27`
- GLPI 11.x: move to `11.0.9`

## From the sources

GLPI is a free asset and IT management software package. From 0.83 until 10.0.27 and from 11.0.0 until 11.0.9, any authenticated user could submit a crafted request to change the visibility of knowledge base items, reminders, or RSS feeds and then access content that should remain restricted. This issue is fixed in versions 10.0.27 and 11.0.9.
