What is CVE-2021-33563?

Koel prior to version 5.1.4 presents multiple vulnerabilities related to authentication processes. Specifically, it lacks login throttling mechanisms, fails to enforce a robust password strength policy, and inadvertently reveals whether a failed login attempt was made with a valid username. These deficiencies can significantly increase the risk of brute-force attacks, allowing malicious actors to exploit the system more easily. Users are strongly encouraged to update to the latest version to mitigate these risks.
