Use of a Cryptographic Primitive with a Risky Implementation Affecting ml-dsa package, versions <0.1.0-rc.3
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.

Upgrade ml-dsa to version 0.1.0-rc.3 or higher.
Overview
Affected versions of this package are vulnerable to Use of a Cryptographic Primitive with a Risky Implementation due to non-constant-time division in the ML-DSA decomposition logic. An attacker can exploit timing differences during ML-DSA signing to gain information about secret-dependent values processed by high_bits() and low_bits(), potentially enabling partial key leakage over many observations.
