Astra Linux – Vulnerability in libmicrohttpd

GNU libmicrohttpd before version 0.9.76 allowed remote Denial of Service attacks due to improper parsing of a multipart/form-data boundary in the postprocessor.c MHDcreatepostprocessor method. This allowed attackers to remotely send a malicious HTTP POST packet that included one or more '\0' byte...

CVE-2026-42854 arduino-esp32: Stack buffer overflow in WebServer multipart boundary parsing leads to remote crash potential RCE

arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. Prior to 3.3.8, the WebServer multipart form parser in arduino-esp32 allocates a Variable Length Array VLA on the stack whose size is derived from an attacker-controlled HTTP head...

CVE-2026-28525

SWUpdate contains an integer underflow vulnerability in the multipart upload parser in mongoosemultipart.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...

SUSE CVE-2026-26961

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Multipart::Parser extracts the boundary parameter from multipart/form-data using a greedy regular expression. When a Content-Type header contains multiple boundary parameters, Rack selects the last one...

Rack's greedy multipart boundary parsing can cause parser differentials and WAF bypass.

Summary Rack::Multipart::Parser extracts the boundary parameter from multipart/form-data using a greedy regular expression. When a Content-Type header contains multiple boundary parameters, Rack selects the last one rather than the first. In deployments where an upstream proxy, WAF, or intermedia...
