KEV: True

Shodan Query: NA

Acceptance Criteria: The template must include a complete POC and should not rely solely on version-based detection. Contributors are required to provide debug data(-debug) along with the template to help the triage team with validation or can also share a vulnerable environment like docker file.

Rewards will only be given once the template is fully validated by the team. Templates that are incomplete or invalid will not be accepted. Avoid adding code templates for CVEs that can be achieved using HTTP, TCP, or JavaScript. Such templates are blocked by default and won’t produce results, so we prioritize creating templates with other protocols unless exceptions are made.

Acceptance Criteria: The template must include a complete POC and should not rely solely on version-based detection. Contributors must share vulnerable setup information or a testable instance by emailing templates@projectdiscovery.io. Providing a testable instance significantly reduces validation time and increases the chance of quicker rewards. Templates that are incomplete, invalid, or non-verifiable will not be accepted. Avoid submitting code templates for CVEs that can be detected using HTTP, TCP, or JavaScript only these are blocked by default and will not produce results. Exceptions may apply for certain cases. Do not submit AI-simulated vulnerable environments. To qualify for the bounty, the team must be able to fully validate the POC. If you have hosted a vulnerable environment for validation, send the details (IP or Docker setup) along with the PR number to templates[at]projectdiscovery.io
