Hi,

The following vulnerability was published for libsoup3.

CVE-2026-0719[0]:
| A flaw was found in libsoup's NTLM (NT LAN Manager) authentication
| module. When NTLM authentication is enabled, a local attacker can
| exploit a stack-based buffer overflow vulnerability in the md4sum()
| function. This allows the attacker to overwrite adjacent memory,
| which may result in arbitrary code execution with the privileges of
| the affected application.


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