Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Moderate
Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs:
hugo:
* hugo-0.160.1-2.hum1 (aarch64, x86_64)
* hugo-0.160.1-2.hum1.src (src)

A flaw was found in Hugo, a static site generator. This vulnerability arises from improper escaping of links and image links within the default markdown to HTML renderer. A remote attacker could exploit this by crafting malicious markdown content, potentially leading to information disclosure or content manipulation when processed by a user.
4.6 (Medium)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://images.redhat.com/
https://access.redhat.com/errata/RHSA-2026:7848
Workaround
To mitigate this issue, ensure that all markdown content processed by Hugo originates from trusted sources. Alternatively, implement custom render hooks for links and images within Hugo to ensure proper escaping, as this configuration prevents exploitation.
