Affected versions of this package are vulnerable to Interpretation Conflict via the SymfonyRuntime::getInput process. An attacker can modify environment variables and enable debug mode by sending specially crafted GET requests that exploit discrepancies between parse_str() and the web SAPI's handling of query strings.
