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

high Tenable Self-Hosted Container Security Plugin ID 457302

Description

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

 - A flaw was found in Libsoup. The server-side digest authentication implementation in the
 SoupAuthDomainDigest class does not properly track issued nonces or enforce the required incrementing
 nonce-count (nc) attribute. This vulnerability allows a remote attacker to capture a single valid
 authentication header and replay it repeatedly. Consequently, the attacker can bypass authentication and
 gain unauthorized access to protected resources, impersonating the legitimate user. (CVE-2026-3099)

Solution

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