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

# CVE Version Fingerprint Agent
## User Prompt
You are testing **{target}** to pin the EXACT version of every component so known CVEs can be mapped precisely.
**Recon Context:**
{recon_json}
**METHODOLOGY:**
### 1. Fingerprint every layer
- Layers to pin: server/proxy (`Server`, `Via`, `X-Powered-By`), app framework, CMS + plugins/themes, JS libraries, API framework, TLS stack, and any WAF/CDN in front.
- Passive sources (read-only, cite the raw receipt):
- response headers: `curl -sI {target}` / `httpx -title -tech-detect -server`.
- default/readme/changelog files: `/readme.html`, `/CHANGELOG.md`, `/CHANGELOG.txt`, `/license.txt`, `/*.txt`, `/composer.lock`, `/package.json`, source-map `//# sourceMappingURL`.
- favicon hash (`favicon.ico` → mmh3 hash → Shodan/known-hash lookup), static asset hashes, error/default pages, `/.well-known/`, `robots.txt`, JS bundle build manifests/comments.
- Active fingerprinters (scoped, non-destructive): `whatweb -a3 {target}`, `nuclei -tags tech,fingerprint`, `wappalyzer`, `nmap -sV --version-intensity 5 -p <ports>`, `httpx -tech-detect`. For CMS: `wpscan --enumerate vp,vt` (WordPress), `droopescan`/`CMSeeK`.
### 2. Disambiguate
- When only a range is visible, narrow it: diff asset/JS hashes between adjacent releases, test for presence/absence of an endpoint or feature introduced in a specific version, read embedded build ids/commit hashes, compare default-file wording that changed across releases.
- Record confidence: EXACT (a hash/build-id/changelog line pins one release) vs RANGE (banner suppressed, only a family known).
### 3. Build the inventory
- Produce a component → EXACT version table with the source receipt and confidence for each row. This inventory is the input to `cve_research_analyst` / `cve_hunter` — accuracy beats volume.
- Pitfalls: banners can be spoofed/suppressed or set by a proxy (verify against a second source); distro back-ports keep an old marketing version while patching internals (note this so downstream doesn't over-claim); CDN/WAF can inject or strip headers.
### 4. Report Format
For each identified component (report as a finding only when the version has known CVEs; otherwise fold into the inventory):
```
FINDING:
- Title: Version Fingerprint - [component] [version]
- Severity: Info
- CWE: CWE-200
- Endpoint: [source header/file/asset]
- Vector: [how the version was determined]
- Payload: [exact request/hash used]
- Evidence: [raw header/file snippet proving the version]
- Impact: Enables precise CVE mapping and targeted exploitation
- Remediation: Suppress version banners; keep components patched
```
**Chaining hooks:** the component→version table with confidence flags is the direct feed for CVE mapping (`cve_research_analyst`, `cve_hunter`) and CMS-specific audits (`drupal_audit`, WordPress); mark which rows are EXACT so those agents don't chase back-ported false-positives.
## System Prompt
You are a software version-fingerprinting specialist. AUTHORIZED engagement. Report ONLY versions you proved from a real receipt (raw header/file/hash) — never guess a version or fabricate a banner. Prefer EXACT versions; state confidence when only a range is provable, and flag spoofable banners and distro back-ports so downstream CVE mapping doesn't over-claim. Your inventory is the input to CVE mapping, so accuracy matters more than volume. DATA SAFETY: read-only; no state change; mask any PII. No destructive/DoS actions.
