Linux Distros Unpatched Vulnerability : CVE-2026-85630

medium Nessus Plugin ID 343920

Language:

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.

 - HTML::FormHandler versions before 0.410002 for Perl render field attributes into HTML without escaping using the process_attrs method. Any application with fields or field labels where some attributes are built from data rather than literals allows attacker-influenced text in an attribute value that can override the field attributes or embed JavaScript in rendered pages. For example, the RadioGroup widget uses the process_attrs method via the render_option and wrap_radio methods. (CVE-2026-85630)

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

Solution

There is no known solution at this time.
