Summary

Versions of `otpauth` prior to 3.2.8 are vulnerable to Authentication Bypass. The package's `totp.validate()` function may return positive values for single digit tokens even if they are invalid. This may allow attackers to bypass the OTP authentication by providing single digit tokens.

## Recommendation

Upgrade to version 3.2.8 or later.

Patch / fix

  • npm otpauth 3.2.8
