# JetBrains Hub: read-only users could change auth group mappings

Link for people: https://infrastack.ai/live/CVE-2026-123300 (this .md is for agents)

In JetBrains Hub before 2026.2.52519, missing authorisation let users with read-only access modify the authentication module's group mappings. An attacker with a read-only account could change which groups users are mapped into, possibly gaining more access than intended.

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

## How to check

- Check the installed Hub version in the Hub administration page; the sources do not name a command.

## Fix

- JetBrains Hub: `2026.2.52519`

## Timeline

- 2026-11-06T11:41:25+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-123300

## From the sources

In JetBrains Hub before 2026.2.52519 missing authorisation allowed users with read-only access to modify auth module group mappings
