Linux Distros Unpatched Vulnerability : CVE-2026-8368
medium Nessus Plugin ID 315716
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- 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)
Note that Nessus relies on the presence of the package as reported by the vendor.
