# JetBrains YouTrack: read-only users could change issue visibility settings

Link for people: https://infrastack.ai/live/CVE-2026-123330 (this .md is for agents)

In JetBrains YouTrack before 2026.2.19562, a missing authorization check let users with read-only access change issue visibility settings. An attacker with a read-only account could alter who can see issues they should not be able to change.

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

## How to check

- Check the installed YouTrack version in the admin panel or with the server's version page; if it is below `2026.2.19562`, the instance is in range.
- Review whether read-only accounts exist on the instance, since they are the only users this flaw needs.

## Fix

- JetBrains YouTrack: upgrade to `2026.2.19562` or later.

## Timeline

- 2026-11-06T11:41:28+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-123330

## From the sources

In JetBrains YouTrack before 2026.2.19562 missing authorization allowed users with read-only access to change issue visibility settings
