The chart below shows the most common weaknesses found in vulnerabilities across the Erlang ecosystem. Understanding which weakness types recur most often helps library authors and application developers focus their security efforts where they matter most.

Each CVE is mapped to its CWE (Common Weakness Enumeration) using the MITRE CWE hierarchy. A slice's count includes every CVE reachable anywhere below it in the hierarchy, not just CVEs assigned that exact CWE — click a slice or legend row to drill into its direct children and see the same breakdown one level down.
