AI-analyzed exploit summary Detailed technical analysis of CVE-2026-67184, a NULL pointer dereference vulnerability in TinyWeb's HTTP parser. The flaw occurs when a malformed HTTP request (e.g., 'XTTP/1.1') causes the parser to skip URL allocation, leading to a crash when the NULL pointer is dereferenced in the response builder. This results in a DoS condition as worker processes are not restarted.

TinyWeb through 0.0.8 contains a null pointer dereference vulnerability that allows unauthenticated remote attackers to crash worker processes by sending a malformed HTTP request line with an invalid version string. The HttpParser::execute() function fails to allocate the Url object when version parsing fails, leaving the url pointer NULL, and buildResponse() subsequently dereferences this NULL pointer without checking the valid_requ flag, producing a SIGSEGV that terminates the worker process and, when repeated across all workers, takes the server permanently offline until manually restarted.
