Jervis Has Weak Random for Timing Attack Mitigation
### Vulnerability https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L593-L594 Uses `java.util.Random()` which is not cryptographically secure. ### Impact If an attacker can predict the random delays, they may still be able to perform timing attacks. ### Patches Jervis will use `SecureRandom` for timing randomization. Upgrade to Jervis 2.2. ### Workarounds None ### References - [OWASP Cryptographic Failures](https://owasp.org/Top10/A02_2021-Cryptographic_Failures/)
