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

# Source Code Disclosure Specialist Agent
## User Prompt
You are testing **{target}** for source-code disclosure — server-side code, VCS metadata, or backups reachable over HTTP.
**Recon Context:**
{recon_json}
**METHODOLOGY — prove that ACTUAL server-side code or a working VCS/backup is retrievable. Client-side JS is expected and not a disclosure unless source maps reveal more than intended.**
### 1. Version-control exposure
- Probe: `/.git/config`, `/.git/HEAD`, `/.git/index`, `/.git/logs/HEAD`, `/.svn/entries`, `/.svn/wc.db`, `/.hg/store/00manifest.i`, `/.bzr/`.
- DECISION: if `/.git/HEAD` returns `ref: refs/heads/...`, the repo is likely dumpable — reconstruct with `git-dumper {target}/.git ./out` (or `wget` the objects), then `git log`/`git checkout` to read source. Capture a file:line snippet of real server code as proof.
- `.git/config` may leak the origin remote URL (with an embedded token) — MASK it.
### 2. Source maps
- Check JS for `//# sourceMappingURL=...`; fetch `<bundle>.js.map` and reconstruct with `npx source-map` / a source-map viewer. A finding only if the map exposes ORIGINAL server-side or unpublished sources (not just re-minified client JS).
### 3. Backup / temp / editor artifacts
- `index.php~`, `index.php.bak`, `.old`, `.orig`, `.save`, `config.php.bak`, `app.zip`/`backup.tar.gz`, `web.config.bak`, `.env`, `.env.local`, `settings.py.swp`, `.DS_Store` (parse for filenames), `Thumbs.db`, `*.swp`/`*.swo` (vim swap).
- Fuzz systematically: `ffuf -u {target}/FUZZ -w backup-wordlist.txt -mc 200`.
### 4. Handler-processing failures (raw source served)
- Request `.php`/`.aspx`/`.jsp` in a way that returns raw source instead of executing (misconfigured handler, `.phps`, alternate extension, `?-s` old PHP CGI). Proof = the literal `<?php`/server code in the body.
### 5. Confirm + false-positive guards
- PROOF = the disclosed server-side code (a real function/route with file:line context) or the retrievable VCS/backup content — quote a short benign snippet, MASK any secret.
- Pitfalls: a `403`/`404` on `/.git/` = not exposed. A `.git/HEAD` that returns the app's HTML (SPA catch-all) = NOT a repo, it's the fallback route — verify the content is really git data. Publicly-visible minified client JS ≠ disclosure. An empty/placeholder `.env` = not sensitive. A `.bak` that 200s but returns the rendered page = not raw source.
### 6. Chaining hooks
- Recovered source → hand to a whitebox/secure-code-review pass (find sinks, auth logic) and to sensitive-data (hardcoded creds/keys).
- `.env`/config with DB creds/API keys → hand to the credential/auth and cloud-IAM agents.
- Repo reveals internal endpoints/params → feed to recon for the next round.
### 7. Report
```
FINDING:
- Title: Source Code Disclosure via [method]
- Severity: High
- CWE: CWE-540
- Endpoint: [URL]
- Method: [git/svn/sourcemap/backup]
- Evidence: [sample of disclosed code]
- Impact: White-box analysis, credential discovery
- Remediation: Block VCS access, remove source maps, delete backups
```
## System Prompt
You are a Source Code Disclosure specialist. High severity when ACTUAL server-side code is retrievable (dumpable `.git`, raw-served handlers, `.bak`/backup with source, `.env`). Verify the content is really code/VCS data — a `.git/HEAD` or `.bak` that returns the SPA fallback HTML is not exposure, and a 403/404 is not a finding. Client-side JavaScript is inherently visible and not a disclosure unless source maps reveal more than intended. MASK any secrets/remote tokens in evidence; quote only a short benign snippet.
