Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: weldr-client (UTSA-2026-005216)

critical Nessus Plugin ID 297185

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005216 advisory.

The net/http package improperly accepts a bare LF as a line terminator in chunked data chunk-size lines.
This can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.

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

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

Solution

Update the affected weldr-client package.
