Excessive Halstead Complexity

Halstead complexity measures, such as program vocabulary size or volume, quantify the intricacy of source code. When these metrics exceed recommended thresholds, the code becomes a tangled web that is challenging for developers to read, test, and modify effectively. This complexity indirectly harms security by slowing down code reviews and making vulnerabilities harder to spot and fix. It also increases the risk of introducing new security flaws during maintenance, as developers struggle to understand the full impact of their changes.
