Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-331: Insufficient Entropy, where the product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. In Paragonie/random compat, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

random_compat versions prior to 2.0 are affected by a security vulnerability related to the insecure usage of Cryptographically Secure Pseudo-Random Number Generators (CSPRNG). The affected versions use openssl_random_pseudo_bytes(), which may result in insufficient entropy and compromise the security of generated random numbers.
