What is CVE-2020-10184?

The verify endpoint in YubiKey Validation Server versions prior to 2.40 lacks proper validation of SQL query lengths, enabling remote attackers to exploit this flaw and potentially cause a denial of service. This vulnerability specifically impacts self-hosted OTP validation services utilizing the server, while YubiCloud users are not affected.
