SCA: security update for distributed (GHSA-c336-7962-wfj2)

medium Tenable Self-Hosted Container Security Plugin ID 436800

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Dask distributed is a distributed task scheduler for Dask. Prior to 2026.1.0, when Jupyter Lab, jupyter-
 server-proxy, and Dask distributed are all run together, it is possible to craft a URL which will result
 in code being executed by Jupyter due to a cross-side-scripting (XSS) bug in the Dask dashboard. It is
 possible for attackers to craft a phishing URL that assumes Jupyter Lab and Dask may be running on
 localhost and using default ports. If a user clicks on the malicious link it will open an error page in
 the Dask Dashboard via the Jupyter Lab proxy which will cause code to be executed by the default Jupyter
 Python kernel. This vulnerability is fixed in 2026.1.0. (CVE-2026-23528)
