Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Expressions can cause exponential stack growth via :each, :fcall, and list literals, leading to resource exhaustion.
Remote Code Execution: Log4j JNDI lookup vulnerability (Log4Shell) allows remote code execution; patched via version bumps.
ReDoS: User-controlled regex in :s legend operator can cause catastrophic backtracking; bounded character reads mitigate.
