SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Bugcrowd submissions often get auto-closed or downgraded because the VRT category defaults to a low severity, triagers map findings to out-of-scope clauses, or chained findings are filed without clear cross-references. This Skill provides the program-specific tactics to file Bugcrowd reports that survive triage. ## Core Features & Use Cases - VRT Search-and-Fallback Strategy: Ordered search hierarchy for picking the most accurate VRT node, with common mappings for IDOR, ATO, rate-limiting, and GraphQL findings, plus a fallback plan when no exact VRT exists. - Manual Severity Override & Severity-Request Paragraph: Instructions for overriding the VRT default in the form and leading the report body with a severity-request paragraph that cites the program's Focus Areas. - OOS-Clause Rebuttal Templates: Ready-made in-scope justification sections for rate-limiting, debug-info, user-enumeration, and theoretical-issue objections. - Use Case: You found a password-verification oracle with no rate limiting on a Bugcrowd program. Use this Skill to pick the right VRT, override the P4 default to P3 with a severity-request paragraph, rebut the "non-authentication endpoint" OOS clause, and cross-reference the chained ATO report. ## Quick Start Help me file a Bugcrowd submission for my finding, including the right VRT category, a severity-request paragraph, and rebuttals to likely out-of-scope objections.

Frequently Asked Questions about bugcrowd-reporting

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I choose the right VRT category on Bugcrowd?▼

Search the VRT dropdown in order: the bug's primary class, the data category exposed, the control bypassed, the endpoint type, then a generic parent node. Pick the highest-severity match that still accurately describes the bug, and use a fallback like Server Security Misconfiguration > Other with a VRT mapping note if nothing fits.

How do I request a higher severity than the Bugcrowd VRT default?▼

Select the accurate VRT, then manually set the Technical Severity field to your requested level. Add a severity-request paragraph as the first body section citing the program's Focus Areas, the chained impact, and why the VRT default's example does not match your finding.

How do I rebut an out-of-scope closure on Bugcrowd?▼

Include an in-scope justification section that quotes the OOS clause and explains why it does not apply. Templates exist for rate-limiting on authentication endpoints, debug-info framing of schema disclosure, user enumeration leaking real PII, and theoretical-issue objections backed by end-to-end PoC evidence.

How should I file chained vulnerabilities on Bugcrowd?▼

File the chain consumer first at the chained severity, then file each primitive as a separate report at its standalone severity within an hour. Cross-reference all linked submission UUIDs in each body, and frame the chain as a severity amplifier rather than a merge request.

When should I not file a Bugcrowd submission?▼

Do not file when you only have an API behavior observation without a demonstrated exploitation path, since theoretical findings damage researcher reputation. Also avoid P1 over-claims, batch-filing many reports at once, and filing OOS-risky findings before establishing credibility with a clean report.
