  - A flaw was found in libsoup. The implementation of HTTP range requests is vulnerable to a resource
    consumption attack. This flaw allows a malicious client to request the same range many times in a single
    HTTP request, causing the server to use large amounts of memory. This does not allow for a full denial of
    service. (CVE-2025-32907)
