Affected versions of this package are vulnerable to Race Condition. The whitespace normalisation using in 1.x and 2.x removes any unicode whitespace. Under certain specific conditions this could potentially allow a malicious user to execute code remotely. How the Exploit Works
Unicode Bypass: The filename exploit\u202Ephp.txt uses the Right-to-Left Override (RLO) character to disguise the file extension.
Malicious File Upload: The file is uploaded and stored on the server.
Payload Execution: If the server allows code execution in the uploads directory, the attacker can run the PHP payload remotely.# CVE-2021-32708 Affected versions of this package are vulnerable to Race Condition.
