Echo: libsoup3: security update to 3.6.6-1+e3

medium Tenable Self-Hosted Container Security Plugin ID 461483

Description

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

 - A flaw was found in libsoup. When handling cookies, libsoup clients mistakenly allow cookies to be set for
 public suffix domains if the domain contains at least two components and includes an uppercase character.
 This bypasses public suffix protections and could allow a malicious website to set cookies for domains it
 does not own, potentially leading to integrity issues such as session fixation. (CVE-2025-4035)

Solution

Update the libsoup3 library and its related packages to version 3.6.6-1+e3 or later.
