Observable Timing Discrepancy Affecting vodozemac package, versions <0.7.0
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 vodozemac to version 0.7.0 or higher.
Overview
Affected versions of this package are vulnerable to Observable Timing Discrepancy through the use of a non-constant time base64 implementation for key material operations. An attacker can infer some information about the secret key material by observing timing variations in the encoding and decoding operations.
Note:
This is only exploitable if the attacker has access to high precision timing measurements and repeated access to the base64 encoding or decoding processes.
