WordPress Plugin Hunt Skill

Discover installed WordPress plugins through REST API namespace probing, readme.txt version detection, and HTML/JS source analysis. Cross-reference discovered versions against known CVEs for exploitation. WordPress plugin vulnerabilities are one of the most reliable paths to RCE — confirmed CVEs include Elementor, Slider Revolution, ElementsKit, Gravity Forms, Jetpack, WooCommerce, and LiteSpeed Cache.

When to Use

• WordPress confirmed on target (via wp-mass-recon).
• Running deep-invade Phase 3.
• You need an exploitation vector beyond CORS/XMLRPC.
• Target has a plugin-heavy WordPress site (e-commerce, page builder, forms).

Prerequisites

• terminal with curl, python3.
• WordPress target confirmed (/wp-json/ or /wp-login.php accessible).
• For CVE exploitation: knowledge of specific CVE PoCs (reference security-arsenal skill).

How to Run

# Quick plugin namespace scan (30+ plugins)
TARGET="example.com"
for ns in "revslider/v1" "elementskit/v1" "elementor/v1" "gf/v2" "wc/v3" \
  "jetpack/v4" "litespeed/v1" "yoast/v1" "acf/v3" "contact-form-7/v1" \
  "solidwp-mail/v1" "wpsl/v1" "redirection/v1" "rankmath/v1"; do
  code=$(curl -sk -o /dev/null -w "%{http_code}" --max-time 5 --connect-timeout 5 "https://$TARGET/wp-json/$ns")
  [[ "$code" != "404" ]] && echo "FOUND: /wp-json/$ns (HTTP $code)"
done

Quick Reference

Top Exploitable Plugins (US SMB targets — confirmed CVEs from mass recon)

| Plugin | Vulnerable Version | CVE | Impact | Frequency |

|--------|-------------------|-----|--------|-----------|

| Slider Revolution | < 6.6.20 | CVE-2024-2534 | RCE via file upload | ~10% |

| ElementsKit | < 2.9.4 | CVE-2023-6851 | SQLi | ~5% |

| ElementsKit | < 2.9.4 | CVE-2023-6853 | File Upload (unauthenticated) | ~5% |

| Gravity Forms | < 2.8.2 | CVE-2024-6115 | PHP Object Injection → Auth Bypass | ~8% |

| Jetpack | < 13.1 | CVE-2024-1782 | SSRF | 28% |

| Elementor | < 3.24.0 | CVE-2024-xxxx | Info disclosure → Auth bypass | 28% |

| LiteSpeed Cache | < 6.5.0 | CVE-2024-50550 | Privilege escalation | ~15% |

| WooCommerce | N/A (API exposure) | N/A | Order/customer data | 42% |

| Yoast SEO | N/A (sitemap enum) | N/A | Author email leak | 42% |

Detection Methods

| Method | What It Reveals | Reliability |

|--------|----------------|-------------|

| REST namespace probe | Plugin presence + data | High (if plugin registers REST routes) |

| readme.txt version | Exact version number | Medium (many sites block readme.txt) |

| HTML source grep | Plugin CSS/JS handles | Medium |

| robots.txt | Plugin-generated entries | Low (only if plugin adds entries) |

| /wp-content/plugins/<slug>/ | Directory listing or assets | Medium |
