Amazon Linux 2 : perl-libwww-perl, --advisory ALAS2-2026-3325 (ALAS-2026-3325)

medium Nessus Plugin ID 319853

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of perl-libwww-perl installed on the remote host is prior to 6.05-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3325 advisory.

 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)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update perl-libwww-perl' or or 'yum update --advisory ALAS2-2026-3325' to update your system.
