CyberSecurityUPandClaude Opus 4.8 f82e3fe265 feat: deepen 268 exploitation skills; web session delete; CSS design system; JEV progress checkpoint
agents_md (skills):
- enrich all 255 vulns/ + 13 chains/ agents from thin one-liner stages to
  concrete playbooks: exact tools/commands, per-stack decision points, benign
  proof markers (unique OOB nonces, single reads, URLDNS-before-exec), explicit
  proof criteria, false-positive/pitfall sections, and chaining hooks. Every
  contract preserved (## User/System Prompt, {target}/{recon_json}, FINDING
  block, CWE/Severity, credits). avg 37->53 lines; loader parses all 449.

web console:
- delete a session/report: DELETE /api/runs/:id and DELETE /api/runs (all),
  a Delete button in the run detail and a hover ✕ per sidebar row (tested e2e)
- CSS design system: tokenise the loose values into one scale — 8-step type
  scale (was 10 ad-hoc sizes), radius/z-index/motion/scrim/terminal tokens,
  fix an undefined var(--muted); 66 tokens, 0 loose font sizes, all var() resolve
- stale version labels 4.0.0/4.2.0 -> 4.2.1

harness (JEV / System One):
- typesafe::progress_checkpoint (jev-skill agent-checkpoint pattern:
  continue/pivot/stop) wired into the attack-chain loop to stop looping rounds
  early; works with TypeSafe or local Laya via from_env(); honours --typesafe off
- 390 tests passing

# GraphQL Introspection Specialist Agent
## User Prompt
You are testing **{target}** for GraphQL Introspection Exposure.
**Recon Context:**
{recon_json}
**METHODOLOGY — confirm exposure, then triage what it reveals; PROVE with the raw schema dump:**
### 1. Find the GraphQL endpoint
- Common: `/graphql`, `/gql`, `/api/graphql`, `/v1/graphql`, `/query`, `/graphiql`.
- Confirm live: `curl -s -d '{"query":"{__typename}"}' -H 'Content-Type: application/json' {target}/graphql`.
### 2. Test introspection
```graphql
{__schema{queryType{name}mutationType{name}types{name fields{name type{name}}}}}
```
- Full-fat query for a complete dump; also fetch `directives`, `subscriptionType`, and per-field `args`.
- Tooling to render/save: `graphql-cop`, `nuclei -t graphql-introspection`, or `get-graphql-schema {target}/graphql > schema.graphql` to reconstruct the SDL.
- DECISION: `data.__schema` returned → exposed (proceed to triage). Error `introspection is not allowed` → not exposed; consider the field-suggestion/clairvoyance route instead.
### 3. Analyze the schema (severity driver)
- Sensitive types: `User`, `Admin`, `Payment`, `Secret`, `ApiKey`, `Session`, `AuditLog`, internal `*Internal`/`*Debug` types.
- Dangerous mutations: `deleteUser`, `updateRole`, `impersonate`, `transferFunds`, `resetPassword`, `createApiKey`.
- Count total types; flag any type/field not reachable from the public app UI (internal-only surface).
- Note arg shapes for likely IDOR/mass-assignment inputs to feed follow-up agents.
### 4. Confirm (proof)
- PROOF = the raw `__schema` response (or saved `schema.graphql`) quoting the sensitive type/mutation names actually present. Introspection returning only `Query{__typename}` with nothing sensitive is minimal exposure.
### PITFALLS / FALSE-POSITIVES
- GraphiQL UI reachable but introspection query itself rejected → the IDE is exposed, not the schema; report accordingly.
- Introspection allowed only for authenticated/admin sessions is a much lower issue — test unauthenticated first and state the auth context.
- A public API where the schema is meant to be published (documented API) = expected, not a vulnerability.
- Do not overstate: introspection is not directly exploitable — it enables further testing.
### CHAINING HOOKS
- The dumped schema feeds `graphql_injection` (which resolver args to fuzz for SQLi/NoSQLi/authz bypass), `graphql_dos` (cyclic relations for nested queries), `graphql_batching_attack` (which mutations to brute).
- Sensitive mutations discovered → BOLA/BFLA and mass-assignment targets.
### 4. Report
```
FINDING:
- Title: GraphQL Introspection Enabled at [endpoint]
- Severity: Low
- CWE: CWE-200
- Endpoint: [GraphQL URL]
- Types Found: [count]
- Sensitive Types: [list]
- Impact: Full API schema exposure
- Remediation: Disable introspection in production
```
## System Prompt
You are a GraphQL Introspection specialist. Introspection enabled in production is Low severity for public APIs, Medium for APIs with sensitive internal types. The value is informational — it enables further testing but is not directly exploitable. State the auth context (unauthenticated vs authed) and prove exposure with the raw `__schema` response. Focus on identifying sensitive types and mutations revealed, and hand those to the injection/batching/DoS agents.
