Hi,

The following vulnerability was published for libsoup3.

CVE-2026-5119[0]:
| A flaw was found in libsoup. When establishing HTTPS tunnels through
| a configured HTTP proxy, sensitive session cookies are transmitted
| in cleartext within the initial HTTP CONNECT request. A network-
| positioned attacker or a malicious HTTP proxy can intercept these
| cookies, leading to potential session hijacking or user
| impersonation.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
