| Package | Affected versions | Patched versions |
|---|---|---|
| oauth | < 0.5.5 | 0.5.5 |
| oauth-ruby | ≤ 0.5.4 |
lib/oauth/consumer.rb in the oauth-ruby gem through 0.5.4 for Ruby does not verify server X.509 certificates if a certificate bundle cannot be found, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information.
