Echo: libsoup3: security update to 3.6.5-8

medium Tenable Cloud Security Plugin ID 462257

Description

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

 - A flaw was found in the libsoup HTTP library that can cause proxy authentication credentials to be sent to
 unintended destinations. When handling HTTP redirects, libsoup removes the Authorization header but does
 not remove the Proxy-Authorization header if the request is redirected to a different host. As a result,
 sensitive proxy credentials may be leaked to third-party servers. Applications using libsoup for HTTP
 communication may unintentionally expose proxy authentication data. (CVE-2026-1539)

Solution

Update the libsoup3 library and its related packages to version 3.6.5-8 or later.
