Common Weaknesses

The most common CWE weakness classes across Erlang ecosystem CVEs

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.

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-362 CWE-362 at MITRE

The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
