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.

to version 5.13.1 or higher.
pyinstaller is a package that bundles a Python application and all its dependencies into a single package
Affected versions of this package are vulnerable to Execution with Unnecessary Privileges. When the tempfile.mkdtemp
function is used, it creates a temporary directory that should only be accessible by the creating user ID. However, on Windows systems, the 0o700 POSIX
permissions mask has no effect, leading to potential security issues. An attacker with local access can interfere with the application by modifying the contents of the temporary directory if it is located in a system-wide location and the application is running in privileged mode with developer mode enabled.
This is only exploitable if the temporary directory base is relocated to a system-wide location (e.g., c:\temp
) and developer mode is enabled on the system.
