Threat Intelligence
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.

CVE-2025-22866 (opens in a new tab)How to fix?
Upgrade std/crypto/internal/nistec to version 1.22.12, 1.23.6, 1.24.0-rc.3 or higher.
Overview
std/crypto/internal/nistec is a Go standard library package std/crypto/internal/nistec
Affected versions of this package are vulnerable to Timing Attack.
Go Vulnerability Report:
due to the use of a variable time instruction in the assembly implementation of the function, a small number of bits of secret scalars may be exposed on the ppc64le architecture. An attacker can potentially infer partial information about secret values by analyzing timing variations. This is only exploitable if the code is running on the ppc64le architecture and the attacker can accurately measure timing differences.
