Hi, The following vulnerability was published for libsoup3. CVE-2026-15714[0]: | An out-of-bounds read vulnerability was found in libsoup's multipart | processing subsystem. The flaw exists in the | soup_multipart_input_stream_read_headers() function inside soup- | multipart-input-stream.c, which does not adequately restrict or | validate the size of incoming multipart boundary strings. When | processing a crafted HTTP response containing a malformed or | oversized boundary parameter, the internal stream reader reads past | the allocated buffer bounds. A remote, unauthenticated attacker can | exploit this behavior to cause a service denial (DoS) through | application failure or potentially read fragments of unauthorized | memory metadata. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
