The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Start learningUpgrade MongoDB.Driver
to version 2.19.0 or higher.
MongoDB.Driver is an Official .NET driver for MongoDB.
Affected versions of this package are vulnerable to Arbitrary Code Execution via ObjectSerializer
when deserializing a compromised object. Exploiting this vulnerability allows a privileged user to cause arbitrary code execution, which may cause further disruption to services.
Note: All of the following conditions must exist to be vulnerable:
Application must be written in C#, take arbitrary data from users and serialize it using _t
, without any validation.
Application must be running on a Windows host using the full .NET Framework, not .NET Core.
Application must have domain model class with a property/field explicitly of type System.Object
or a collection of type System.Object
(against MongoDB best practice).
A malicious attacker must have unrestricted insert access to the target database to add a _t
discriminator.
