29-
- Examine the full HTTP request body to identify the specific attack payload variant (constructor chain, __proto__ access, or malformed references).

- Identify the target application and verify if it runs vulnerable React or Next.js versions.
3131
- Review the source IP for other reconnaissance or exploitation attempts against web applications.
3232
- Check if any proof-of-exploitation files were created on the server (common RCE validation technique).
3333
- Correlate with process execution logs to identify if child processes were spawned by the web server.

### False positive analysis

37-
- Legitimate React Server Components traffic may contain `$ACTION_` patterns but should NOT contain `constructor`, `__proto__`, or malformed references like `$N:a:a` as property paths.

- Legitimate React Server Components traffic may contain specific patterns but should NOT contain constructor strings, or malformed references as property paths.

- Developer testing or security scanning tools may trigger this rule during authorized penetration testing.
39-
- The combination of `$ACTION_REF` with prototype-related strings is a strong indicator of exploitation attempt.
39+
- The combination of constructor or prototype strings with specific patterns is highly indicative of malicious activity.
