Fedora 44 : perl-HTML-FormHandler (2026-21850d7df0)

critical Nessus Plugin ID 349773

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-21850d7df0 advisory.

 HTML::FormHandler versions before 0.410002 for Perl render field attributes into HTML without escaping using the process_attrs method (CVE-2026-85630) . This update fixes that issue.

 ----

 HTML::FormHandler versions through 0.40068 allow attacker selected method dispatch and resource exhaustion because _apply_actions and add_error use error message text built from request data as a Locale::Maketext bracket notation template.

 Versions 0.410000+ fix the issue by passing error messages with request data as Locale::Maketext arguments instead of templates.



Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected perl-HTML-FormHandler package.
