TinyWeb Integer Overflow

Integer overflow in TinyWeb before 2.03.

TinyWeb versions prior to 2.04 fail to properly sanitize control characters and encoded sequences (CR, LF, NUL) in HTTP request headers, allowing attackers to inject malicious values into CGI environment variables and bypass parser validation. This network-accessible vulnerability enables header injection attacks that could lead to data corruption or denial of service without requiring authentication. No patch is currently available for affected deployments.
