In the 3.0.0-alpha.2 release, developers introduced new routing mechanisms and file-parsing logic designed to optimize flat-file rendering. However, certain query parameters or HTTP headers lacked strict validation. Attackers discovered that they could inject payload strings containing directory traversal sequences (like ../ ) or template manipulation syntax. 2. Attack Vectors Pico 3.0.0-alpha.2 Exploit
