Hi, The following vulnerability was published for libsoup3. CVE-2026-1539[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
