Vue d’ensemble

Bugcrowd-specific reporting tactics complementing report-writing: VRT category search-and-fallback strategy when no exact match exists, manual severity override when VRT defaults underrate impact, severity-request paragraph as first body section, OOS-clause rebuttal templates (rate limiting on auth-flow endpoints, debug-info framing, user-enumeration with sensitive PII, theoretical-issue counter), chained-finding cross-reference patterns, target selection for QA-vs-prod programs, researcher-side hygiene (Bugcrowdninja email alias, account state restoration, friendly-tester posture). Use when filing a Bugcrowd submission, when VRT default seems wrong, when triager closes as OOS or downgrades severity, when chaining linked submissions, or when scope distinguishes production from QA. Pairs with report-writing and triage-validation.

BUGCROWD REPORTING — Program-Specific Tactics

Companion to the generic report-writing skill. Use when working specifically on Bugcrowd submissions where VRT mapping, OOS-clause rebuttals, or per-program target selection matter.

This skill encodes patterns that apply specifically to Bugcrowd's submission flow. For the generic per-platform templates (HackerOne / Bugcrowd / Intigriti / Immunefi report bodies), use the report-writing skill. For the 7-Question Gate before deciding to report at all, use triage-validation.

1. VRT Category Selection — Search & Fallback Strategy

Bugcrowd's submission form requires a single VRT (Vulnerability Rating Taxonomy) selection. The dropdown's default severity is bound to the chosen node — pick wrong and the form auto-suggests a lower priority (often P4) when the actual impact is P3 or P2.

Note: VRT default severities are not fixed constants. Bugcrowd revises the VRT schema across versions, and individual programs can remap defaults via their own priority configuration. The P-values shown in the examples below (e.g., "No Rate Limiting on Form → Login" defaulting to P4) are the typical baseline at time of writing — always read the severity the current form actually auto-suggests for this program rather than assuming the value here.

1.1 Search hierarchy (try in order, pick the highest-severity match that still describes the bug)

For any finding, search the VRT dropdown with these terms in this order:

The bug's primary class — e.g., IDOR, XSS, SSRF, auth bypass, 2FA bypass
The data category exposed — e.g., PII, sensitive data exposure, disclosure of secrets
The control bypassed — e.g., broken access control, authentication bypass
The endpoint type — e.g., no rate limiting on form > login, no rate limiting on form > change password
The generic parent node — e.g., Server Security Misconfiguration > Other, Broken Access Control > Other

1.2 Pick the highest-severity match that still accurately describes the bug

Never select a VRT that misrepresents the bug just to get a higher default severity. Triagers will reassign and may flag the misrepresentation. The discipline is: pick the most specific accurate VRT, then use §2 (Manual Severity Override) if the default is wrong.

1.3 Common mappings worth knowing

Finding type	First-choice VRT	Fallback
ATO via missing 2FA on password change	Broken Authentication & Session Management → Second Factor Authentication (2FA/MFA) → Bypass	Broken Auth → Authentication Bypass → Other
Password oracle without rate limit	Broken Authentication & Session Management → Authentication Bypass → Other	Server Security Misconfiguration → No Rate Limiting on Form → Login
GraphQL introspection / APQ allowlist bypass	Server Security Misconfiguration → Other (justify in body)	Broken Access Control → Other
Username → real name PII enumeration	Sensitive Data Exposure → PII Leakage / Disclosure of Secrets → Non-Corporate User	Broken Access Control → Other
State desync on security-sensitive action	Application-Level DoS → Other (with state-desync framing)	Server Security Misconfiguration → Other
Email/SMS pumping on auth-flow endpoint	Server Security Misconfiguration → No Rate Limiting on Form → Email-Triggering / SMS-Triggering	Server Security Misconfiguration → No Rate Limiting on Action
Token brute-force (email-change OTP, password reset)	Broken Authentication → Authentication Bypass → Other	Server Security Misconfiguration → No Rate Limiting on Action

1.4 If no good VRT exists

Pick Server Security Misconfiguration → Other or Broken Access Control → Other and lead the description body with a "VRT mapping note" explaining why the chosen node is the closest available match and what the bug actually is.

2. Manual Severity Override

Bugcrowd's form lets you manually set Technical Severity separate from the VRT default. The form text itself states: "A severity rating suggested by the VRT is not guaranteed to be the severity rating applied to your submission."

2.1 When to override

Override the VRT default when:

The chained outcome is a higher severity than the standalone bug class (chain → ATO)
The VRT category is approximate and its default doesn't reflect the actual impact class
The program's own Focus Areas explicitly list this outcome at a higher severity than VRT's default
The data class exposed is more sensitive than the VRT's example uses (e.g., real-name PII vs. handle enumeration)

2.2 How to override (form mechanics)

Select the VRT that most accurately describes the bug (per §1)
Note the auto-suggested severity (P4, P3, etc.)
In the Technical Severity field, manually pick the severity you're requesting
Add a Severity Request paragraph as the FIRST section of the description body (per §3)

2.3 Don't over-claim

P1 inflation is the fastest way to lose triager trust. Reserve P1 for ATO without interaction, RCE, mass PII exfiltration, fund theft, and similar Critical-bucket impacts. If the chain to P1 requires a separate stolen-cookie premise, file the standalone primitive at P3 and discuss the chain explicitly with cross-references (per §4).

3. Severity-Request Paragraph — Always First in the Body

When the VRT default underrates impact, the FIRST section of the description body should be a severity-request paragraph. This is the first thing the triager reads and it pre-empts the auto-close that often happens when triagers see "P4" in the form.

3.1 Template

## Severity request — please review carefully before applying VRT default

The closest VRT category for this finding is "[chosen VRT]," which Bugcrowd defaults to **P[N] ($X-$Y in [program]'s rubric)**. **I am requesting evaluation at P[M] [standalone | in chain with submission XXXX]** for the following reasons:

1. **[Impact axis 1]** — [specific reason this finding exceeds the VRT default's example]
2. **[Impact axis 2]** — [specific reason, often citing the program's own Focus Areas]
3. **[Impact axis 3]** — [specific reason, often comparing to historical bounty payouts for the same data class]

[Optional: one paragraph contrasting the VRT default's typical example with this finding's actual impact, e.g., "P4 = No Rate Limiting on Login Form" applies to ordinary login pages where brute force is bounded by lockout policies; this endpoint has neither lockout nor throttle.]

3.2 Worked example pattern

## Severity request — please review carefully before applying VRT default

The closest VRT category for this finding is "No Rate Limiting on Form → Login," which Bugcrowd defaults to **P4 ($XX–$YY in this program's rubric)**. **I am requesting evaluation at P3 standalone, P2 in chain with submission XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX** for the following reasons:

1. **[Endpoint] is a password-disclosure oracle, not a generic rate-limit gap.** The endpoint returns true/false for a supplied password — combined with cookie theft, it is the exact primitive an attacker uses to learn the victim's *durable* credential from a stolen *transient* session.
2. **The chained outcome is "Account Takeover,"** explicitly listed under the program → Focus Areas → Critical (P1) examples. This finding is one of two independent links that make that chain work; the other is submission XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX.
3. **The two findings have independent fix surfaces.** Per the program's "one fix = one bounty" rule they should be evaluated as two separate findings whose chain raises the joint severity.

The "P4 = No Rate Limiting on Login Form" default applies to ordinary login pages where brute-force is bounded by lockout policies. This endpoint has neither lockout nor throttle, and the result of brute force is the *user's actual password* (not a session) — making the impact significantly higher than the default VRT severity assumes.

3.3 Tone guidelines

Open with "Severity request — please review carefully before applying VRT default" (literal phrase). Triagers recognize this and don't auto-close.
Use bold sparingly; one or two phrases per reason at most.
Never use "could potentially" or "may allow" — these are downgrade-bait.
Cite the program's own Focus Areas / accepted-impact list by exact name.
Cross-reference linked submissions by full submission ID (UUID format).

4. OOS-Clause Rebuttals — Templates

Bugcrowd triagers sometimes auto-close findings by mapping them to an OOS clause without reading the report. Pre-empt this by including an In-scope justification section that quotes the OOS clause and explains why your finding doesn't fit it.

4.1 "Rate limiting on non-authentication endpoints" rebuttal

When the finding is on an authentication endpoint (login, password change, password verify, OTP verify, token validate):

## In-scope justification

The program OOS list excludes "Rate limiting or brute-force issues on **non-authentication** endpoints." `[endpoint name]` is the canonical authentication endpoint — it accepts a password/token/OTP and returns whether it matches the user's stored credential. By definition this is an authentication primitive. The OOS clause's "non-authentication" qualifier therefore does NOT apply.

4.2 "Debug information disclosure" rebuttal (for schema/introspection findings)

When the finding involves schema disclosure that's actually a control bypass (e.g., GraphQL allowlist bypass exposing the mutation surface):

## In-scope justification

This is not a "debug information" finding. The [persisted-query allowlist | introspection gate | etc.] is acting as an authorization control on the [GraphQL surface | API tree | etc.]. The bypass converts that gate into a no-op — multiple [mutations | endpoints] become reachable that the official clients cannot invoke. The schema disclosure is incidental; the impact is **mutation-surface unlock**, not information leakage.

4.3 "User enumeration with low-risk information" rebuttal

When the finding leaks more than just "this handle/email exists":

## In-scope justification

The program OOS list excludes "User Enumeration issues with **low-risk and insignificant** information being enumerated." The data leaked here is **neither low-risk nor insignificant**: it includes the matched user's [full real first name, last name, profile photo / SSN last 4 / phone number / etc.]. Real-[name | identity | etc.] knowledge is the same data class that gates the program's own [account-recovery flows / fraud-investigation interviews / support-call verification], which means this lookup directly defeats one of the program's own anti-fraud controls. This is PII disclosure, not handle enumeration.

4.4 "Theoretical issues / not exploitable" rebuttal

When the finding's exploitability has been demonstrated end-to-end:

Skill purpose: Bugcrowd-specific reporting tactics complementing report-writing: VRT category search-and-fallback strategy when no exact match exists, manual severity override when VRT defaults underrate impact, severity-request paragraph as first body section, OOS-clause rebuttal templates (rate limiting on auth-flow endpoints, debug-info framing, user-enumeration with sensitive PII, theoretical-issue counter), chained-finding cross-reference patterns, target selection for QA-vs-prod programs, researcher-side hygiene (Bugcrowdninja email alias, account state restoration, friendly-tester posture). Use when filing a Bugcrowd submission, when VRT default seems wrong, when triager closes as OOS or downgrades severity, when chaining linked submissions, or when scope distinguishes production from QA.

Vue d’ensemble

BUGCROWD REPORTING — Program-Specific Tactics

1. VRT Category Selection — Search & Fallback Strategy

1.1 Search hierarchy (try in order, pick the highest-severity match that still describes the bug)

1.2 Pick the highest-severity match that still accurately describes the bug

1.3 Common mappings worth knowing

1.4 If no good VRT exists

2. Manual Severity Override

2.1 When to override

2.2 How to override (form mechanics)

2.3 Don't over-claim

3. Severity-Request Paragraph — Always First in the Body

3.1 Template

3.2 Worked example pattern

3.3 Tone guidelines

4. OOS-Clause Rebuttals — Templates

4.1 "Rate limiting on non-authentication endpoints" rebuttal

4.2 "Debug information disclosure" rebuttal (for schema/introspection findings)

4.3 "User enumeration with low-risk information" rebuttal

4.4 "Theoretical issues / not exploitable" rebuttal
