Amazon Linux 2 : perl-HTTP-Tiny, --advisory ALAS2-2026-3326 (ALAS-2026-3326)

medium Nessus Plugin ID 319846

Synopsis

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

Description

The version of perl-HTTP-Tiny installed on the remote host is prior to 0.033-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3326 advisory.

 HTTP::Tiny versions before 0.093 for Perl do not validate CRLF in HTTP request lines or control field header values.

 The unvalidated inputs are the method and URI in the request line, the URL host that becomes the `Host:` header, and HTTP/1.1 control data field values.

 An attacker who controls one of these inputs, for example a user supplied URL passed to a webhook or URL fetch endpoint, can inject additional headers and smuggle requests to the upstream server. (CVE-2026-7010)

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-HTTP-Tiny' or or 'yum update --advisory ALAS2-2026-3326' to update your system.
