These are predictable or low-entropy sources that are unsuitable for security purposes. Problem types ------------- - CWE-340 Generation of Predictable Numbers or Identifiers - CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator Workarounds ----------- Apply the patch, which requires an upgrade to Mojolicious 9.46 or later.
