Hi, The following vulnerability was published for libsoup3. CVE-2026-66339[0]: | A flaw was found in libsoup. After a CONNECT tunnel is established | through an HTTP proxy, libsoup incorrectly attaches the Proxy- | Authorization header to subsequent HTTPS requests sent through that | tunnel to the destination server. This allows the destination server | to capture proxy credentials, leading to information disclosure. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
