# JetBrains Datalore: view-only collaborators can modify shared workspace content

Link for people: https://infrastack.ai/live/CVE-2026-123284 (this .md is for agents)

Before Datalore 2026.4, a workspace move did not check authorisation properly, so a collaborator with view-only access could change shared content. The sources do not describe a remote exploit path.

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

## How to check

- Check the installed Datalore version against the fixed release 2026.4 in the vendor's release notes.

## Fix

- Move to Datalore `2026.4` or later.

## Timeline

- 2026-11-06T11:41:24+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-123284

## From the sources

In JetBrains Datalore before 2026.4 improper authorisation on workspace moves allowed view-only collaborators to modify shared content
