SCA: security update for eml_parser (GHSA-fxgq-9m89-cxj9)

medium Tenable Self-Hosted Container Security Plugin ID 446266

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 3.0.2, the clean_found_uri function in
 eml_parser/parser.py validates potential URL strings before unescaping HTML entities used for colon,
 slash, or period characters. Valid encoded URLs and their host names are therefore rejected and omitted
 from the extracted URL and domain lists. Email security gateways and SOC pipelines that use those lists as
 indicators of compromise may fail to submit the hidden URLs to threat intelligence feeds, reputation
 services, or sandboxes, allowing malicious links to bypass inspection. This issue is fixed in version
 3.0.2. (CVE-2026-55618)

Solution

Update the eml_parser library and its related packages to version 3.0.2 or later.
