Linux Distros Unpatched Vulnerability : CVE-2026-58402

medium Nessus Plugin ID 325437

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- Hugo is a static site generator. From 0.60.0 until 0.163.3, Hugo's default code-block renderer wrote the Markdown code-fence language or info-string into the code class=language- data-lang= wrapper without HTML escaping. A fence info-string containing a quote and a script payload breaks out of the attribute and injects a live script element. This issue is fixed in 0.163.3. (CVE-2026-58402)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
