GHSA-rmmc-8cqj-hfp3
- Affected
- npm otpauth < 3.2.8
- Fixed in
- 3.2.8· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 3.2.8 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
