FAQ
What does this tool tell you?
The CWE ID Validator checks whether a CWE identifier follows the correct CWE-N format and links to the MITRE CWE entry. Covers the CWE vs CVE distinction and common weakness categories.
What affects the result most?
Format: CWE-N (prefix + numeric ID). Top 25 CWEs cover majority of critical vulnerabilities. CWE = weakness class, CVE = specific instance.
How should I use the result?
Treat the tool's output as a first-pass check, not a proof of correctness. A clean pass means no issues in the patterns this tool recognizes; a failure points to a specific problem you can investigate in your source. The underlying spec is the authoritative source for edge cases.
