Hi, The following vulnerability was published for libsoup3. CVE-2026-15713[0]: | A vulnerability was found in libsoup's HTTP/2 protocol | implementation. The library fails to correctly release memory | context blocks under specific stream termination conditions, such as | when an HTTP/2 connection encounters window exhaustion or explicit | stream resets. A remote, unauthenticated attacker acting as a | malicious network peer can trick the connection engine into | allocating stream states that are subsequently leaked during | cleanup. Over a sustained period, this flaw allows the remote | attacker to consume the system's heap allocations incrementally, | triggering a denial of service (DoS) through an ultimate Out-of- | Memory (OOM) application crash. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
