CVE-2022-23472Network attack vector

Password prediction via non-cryptographic random sampling

Published Dec 6, 2022 · Updated Apr 23, 2025

Weak random generation in Arjun Sharda Passeo before 1.0.5 allows attackers to predict passwords created by the package. The generate method builds a character pool and passes it to Python's non-cryptographic random.sample function, exposing generated values to PRNG prediction. Exploitation requires a password from an affected release to protect an account; successful prediction discloses the secret used for authentication.
