Echo: libwww-perl: security update to 6.78-1+e1

medium Tenable Cloud Security Plugin ID 462737

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - LWP::UserAgent versions before 6.83 for Perl leak Authorization and Proxy-Authorization headers on cross-
 origin redirects. On a 3xx response, the redirect handler strips only Host and Cookie before issuing the
 follow-up request. Caller-supplied Authorization and Proxy-Authorization headers are sent unchanged to the
 redirect target, including across scheme, host, or port changes. A redirect to an attacker controlled host
 therefore discloses the caller's credentials to that host. (CVE-2026-8368)

Solution

Update the libwww-perl library and its related packages to version 6.78-1+e1 or later.
