# Craft CMS: low-privilege users can browse volumes they should not see

Link for people: https://infrastack.ai/live/CVE-2026-124431 (this .md is for agents)

Craft CMS versions from 5.10.0 before 5.11.2 let an authenticated low-privileged user browse volumes they lack permission for. An attacker can delete a linked asset and use the replacement volume browser to list directory structures across all volumes, though not read file contents.

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

## How to check

- Check the installed Craft CMS version in `composer.lock` or by running `./craft version`
- Confirm whether any user accounts have low-privilege roles with asset access

## Fix

- Craft CMS: move to `5.11.2` or later

## Timeline

## From the sources

Craft CMS from 5.10.0 before 5.11.2 contains an authorization bypass vulnerability that allows authenticated low-privileged users to browse volumes they lack permissions for. Attackers can delete a linked asset and use the replacement volume browser modal to view directory structures of all volumes, though not file contents.
