CVE-2024-21493

Summary

CVE-2024-21493 is a vulnerability affecting all versions of the package github.com/greenpau/caddy-security. This issue arises due to improper validation of array index during the parsing of a Caddyfile.

The ensuing panics during configuration file parsing can result in ambiguity and potential security vulnerabilities, compromising the correct interpretation and configuration of the web server.
