CVE-2026-28497

CRITICAL

9.1

Description

TinyWeb is a web server (HTTP, HTTPS) written in Delphi for Win32. Prior to version 2.03, an integer overflow vulnerability in the string-to-integer conversion routine (_Val) allows an unauthenticated remote attacker to bypass Content-Length restrictions and perform HTTP Request Smuggling. This can lead to unauthorized access, security filter bypass, and potential cache poisoning. The impact is critical for servers using persistent connections (Keep-Alive). This issue has been patched in version 2.03.
