Whether a violation of this rule is exploitable depends on what classes are on the JVM's classpath. (Note that this is a property of the execution environment, not of the code being audited.) In the worst case, it could lead to remote execution of arbitrary code.
Rule | Severity | Likelihood | Remediation Cost | Priority | Level |
