CVE-2026-110656
Low · 3.1
CWE-125 Oct 14, 2026
miniupnpc through 2.3.3 Heap Out-of-Bounds Read via minixml parseelt
miniupnpc through 2.3.3 contains a one-byte heap out-of-bounds read vulnerability in the minixml parseelt function's namespace-prefix handling that skips an end-of-buffer check after advancing past ':'. A malicious or spoofed UPnP gateway on the local network can send a device description or SOAP reply ending in ':' within an element name to crash the client.

miniupnpc through 2.3.3 Heap Out-of-Bounds Read via minixml parseatt
miniupnpc through 2.3.3 contains a one-byte heap out-of-bounds read vulnerability in the minixml parseatt function that allows malicious UPnP gateways to read past buffer bounds via crafted replies. Attackers on the local network can spoof a gateway serving device descriptions or SOAP responses ending in '=' to crash the client.
CVE-2026-107159
Medium · 6.5
CWE-369 Oct 7, 2026
MiniUPnPd through 2.3.11 Divide-by-Zero DoS via SSDP M-SEARCH MX Header
MiniUPnPd through 2.3.11 built with --strict contains a divide-by-zero vulnerability in ProcessSSDPData() that allows unauthenticated local network attackers to crash the daemon. Attackers can send a single multicast M-SEARCH datagram with MX: 0 and a known ST to port 1900, triggering SIGFPE and denying UPnP IGD service.
CVE-2026-5720
Critical · 9.1
CWE-125 Apr 17, 2026
miniupnpd Integer Underflow SOAPAction Header Parsing
miniupnpd contains an integer underflow vulnerability in SOAPAction header parsing that allows remote attackers to cause a denial of service or information disclosure by sending a malformed SOAPAction header with a single quote. Attackers can trigger an out-of-bounds memory read by exploiting improper length validation in ParseHttpHeaders(), where the parsed length underflows to a large unsigned value when passed to memchr(), causing the process to scan memory far beyond the allocated HTTP request buffer.
