silverstripe-omnipay is a SilverStripe integration with Omnipay PHP payments library. For a subset of Omnipay gateways (those that use intermediary states like `isNotification()` or `isRedirect()`), if the payment identifier or success URL is exposed it is possible for payments to be prematurely marked as completed without payment being taken. This is mitigated by the fact that most payment gateways hide this information from users, however some issuing banks offer flawed 3DSecure implementations that may inadvertently expose this data. The following versions have been patched to fix this issue: `2.5.2`, `3.0.2`, `3.1.4`, and `3.2.1`. There are no known workarounds for this vulnerability.

Smokescreen is an HTTP proxy. The primary use case for Smokescreen is to prevent server-side request forgery (SSRF) attacks in which external attackers leverage the behavior of applications to connect to or scan internal infrastructure. Smokescreen also offers an option to deny access to additional (e.g., external) URLs by way of a deny list. There was an issue in Smokescreen that made it possible to bypass the deny list feature by surrounding the hostname with square brackets (e.g. `[example.com]`). This only impacted the HTTP proxy functionality of Smokescreen. HTTPS requests were not impacted. Smokescreen version 0.0.4 contains a patch for this issue.
