A vulnerability exists in HybridAuth versions through 3.12.2, specifically within the SSL Handler component in the file src/HttpClient/Curl.php. The issue arises from the default cURL options, which disable SSL certificate verification. This flaw can lead to man-in-the-middle (MITM) attacks during OAuth or OpenID Connect authentication processes. The vulnerability can be exploited remotely, without authentication, but requires a complex attack strategy.
