Chainguard: tensorflow-cpu-jupyter: security update to 2.21.0-r14

high Tenable Cloud Security Plugin ID 477161

Description

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

- The nbconvert tool, jupyter nbconvert, converts Jupyter notebooks to various other formats via Jinja
templates. From 5.4.0 until 7.17.2, ExtractOutputPreprocessor in nbconvert/preprocessors/extractoutput.py
joins the attacker-controlled cell output metadata filename to output_files_dir without limiting the
result to the intended directory. When a victim converts a malicious notebook with the markdown, LaTeX,
reStructuredText, or AsciiDoc exporter, path traversal in the output filename can write attacker-
controlled output data to arbitrary locations accessible to the victim. Running the notebook cell again
replaces the malicious output metadata, but merely converting the supplied notebook does not. This issue
is fixed in version 7.17.2. (CVE-2026-114140)

Solution

Update the tensorflow-cpu-jupyter library and its related packages to version 2.21.0-r14 or later.
