CVE-2026-28525 (GCVE-0-2026-28525)
Vulnerability from cvelistv5
Published
2026-04-23 20:59
Modified
2026-07-28 01:48
CWE
  • CWE-191 - Integer Underflow (Wrap or Wraparound)
  • CWE-125 - Out-of-bounds Read
Summary
SWUpdate contains an integer underflow vulnerability in the multipart upload parser in mongoose_multipart.c that allows unauthenticated attackers to cause a denial of service by sending a crafted HTTP POST request to /upload with a malformed multipart boundary and controlled TCP stream timing. Attackers can trigger an integer underflow in the mg_http_multipart_continue_wait_for_chunk() function when the buffer length falls within a specific range, causing an out-of-bounds heap read past the allocated receive buffer to a local IPC socket.
