SCA: security update for mercury (GHSA-2658-85cv-9wwq)

medium Tenable Cloud Security Plugin ID 476184

Description

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

 - Mercury is a Python framework for sharing Jupyter notebooks as web applications and dashboards. From 3.0.0
 until 3.2.11, mr.Markdown converts attacker-controlled Markdown to HTML without sanitizing raw HTML before
 assigning it to an ipywidgets.HTML sink. Event-handler attributes and other active HTML can therefore
 reach the DOM and execute when another user views the application. This issue is fixed in version 3.2.11.
 (CVE-2026-111059)

Solution

Update the mercury library and its related packages to version 3.2.11 or later.
