SCA: security update for eml-parser (GHSA-389r-rccm-h3h5)

medium Tenable Self-Hosted Container Security Plugin ID 438365

Description

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

 - eml_parser serves as a python module for parsing eml files and returning various information found in the
 e-mail as well as computed information. Prior to version 2.0.1, the official example script
 examples/recursively_extract_attachments.py contains a path traversal vulnerability that allows arbitrary
 file write outside the intended output directory. Attachment filenames extracted from parsed emails are
 directly used to construct output file paths without any sanitization, allowing an attacker-controlled
 filename to escape the target directory. This issue has been patched in version 2.0.1. (CVE-2026-29780)

Solution

Update the eml-parser library and its related packages to version 2.0.1 or later.
