0 CVE-2026-54571 is an integer overflow vulnerability in the ESPAsyncWebServer library versions prior to 3.11.1. The issue occurs in the multipart/form-data parser where an 8-bit boundary position counter wraps around when processing a 256-byte multipart boundary. This causes the boundary parsing loop to never terminate, leading to excessive CPU usage and triggering a FreeRTOS watchdog reset on ESP32 and ESP8266 devices. The vulnerability is fixed in version 3.11.1. Join the discussion | CVE Database V5 | 09/17/2026, 18:28:26 UTC Added: 09/17/2026, 18:47:19 UTC |
