Bugcrowd Reporting Tactics

A Bugcrowd-specific reporting overlay: VRT selection, manual severity-override requests, and ready-made out-of-scope rebuttals.

Security & ReviewAdvanced★ 4,976⑂ 757AI score 8/10Last updated: Oct 11, 2026

What it does

  • VRT selection strategy: search the dropdown in order (bug class → data exposed → control bypassed → endpoint type → generic parent) and pick the highest-severity node that still accurately describes the bug, plus a mapping table for common finding types.
  • Manual severity override: when to override the VRT default and a template for the "Severity request" paragraph that goes first in the report body.
  • OOS-clause rebuttals: fill-in templates for the four most common auto-closes — rate limiting on auth endpoints, "debug information", low-risk user enumeration, and "theoretical/not exploitable".
  • Chained findings: filing order (primitives first, consumer second), bidirectional UUID cross-reference blocks, and "one fix = one bounty" framing.
  • Researcher hygiene: bugcrowdninja email alias, post-PoC account restoration, session rotation, locked-account etiquette.

Who it's for

  • Bug bounty hunters actively filing on Bugcrowd
  • Researchers whose reports keep getting downgraded to P4 or closed as out of scope
  • Anyone working programs that scope both production and QA assets

Examples

  1. A password-verify endpoint with no rate limit: keep the accurate VRT ("No Rate Limiting on Form → Login", default P4) and generate a severity-request paragraph asking for P3 standalone / P2 in chain.
  2. A triager closes your report citing "rate limiting on non-authentication endpoints is OOS": drop in the §4.1 rebuttal proving the endpoint is an authentication primitive.
  3. Password oracle + missing step-up = ATO: file both primitives first to obtain UUIDs, then file the chain consumer with a filled-in "Chain partners" block and backfill each primitive.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/bugcrowd-reporting folder from the GitHub repo elementalsouls/Claude-BugHunter into my ~/.claude/skills/bugcrowd-reporting/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/elementalsouls/Claude-BugHunter.git && mkdir -p ~/.claude/skills && cp -r Claude-BugHunter/skills/bugcrowd-reporting ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/elementalsouls/Claude-BugHunter.git
  3. Create the skills directory if needed: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r Claude-BugHunter/skills/bugcrowd-reporting ~/.claude/skills/
  5. Also copy the companion skills it expects: report-writing, triage-validation, evidence-hygiene.
  6. Restart Claude Code and try: "Pick the VRT and draft a severity-request paragraph for this Bugcrowd submission."
  7. Remember that VRT node names and default P-levels change over time — verify against what the live submission form actually suggests.
