Source: libsoup3
Version: 3.6.6-1

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.

Please adjust the affected versions in the BTS as needed.
