# JetBrains YouTrack: untrusted remote code runs through plugin sandbox page

Link for people: https://infrastack.ai/live/CVE-2026-123325 (this .md is for agents)

Before the fixed builds, YouTrack allowed untrusted remote code to be included through its plugin sandbox page. An attacker who gets a user to reach that page can run code in the context of the YouTrack session.

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

## How to check

- Check the running YouTrack version against the fixed builds listed in the fix field.
- Look at the YouTrack version under Administration > Global Settings or the About dialog: unknown if the sources do not say more.

## Fix

- YouTrack `2025.3.170763` or later on the 2025.3 line
- YouTrack `2026.1.14150` or later on the 2026.1 line
- YouTrack `2026.2.19656` or later on the 2026.2 line

## Timeline

- 2026-11-06T11:41:27+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-123325
