Hi, The following vulnerability was published for libsoup3. CVE-2026-85197[0]: | A flaw was found in libsoup. A malicious HTTP/2 server or a Man-in- | the-Middle (MITM) attacker can exploit a heap use-after-free | vulnerability in the HTTP/2 client implementation. This occurs when | a GNOME application uploads a file using HTTP/2, and the server | sends a GOAWAY frame while the file body is being read | asynchronously. This can lead to memory corruption, potentially | resulting in information disclosure or arbitrary code execution. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
