TinyWeb 0.0.8 Memory Leak DoS via HTTP Request Handling
CVE-2026-67183
Description
TinyWeb through 0.0.8 contains a memory leak vulnerability that allows unauthenticated attackers to exhaust available memory by sending ordinary well-formed HTTP requests. Each request causes HttpParser::execute() to allocate Url objects, HttpHeaders objects, and HttpHeader instances via raw new expressions that are never freed due to missing destructors and unreachable delete calls, causing worker resident memory to grow monotonically by approximately 20 to 28 kB per request until the worker process is killed.
