exploitability-analyzer

exploitability-analyzer is a skill for Claude Code, Codex from ArabelaTso/Skills-4-SE. It costs 127 tokens per session (3,370 once invoked), scanned A, original, Apache-2.0.

A security-analysis skill that checks whether a reported vulnerability can actually be reached and used by an attacker. It examines inputs, code paths, sanitization, and the program's execution context.

In plain words
What is it for?
Use it to assess issues such as SQL injection, cross-site scripting, and command injection, including their likely impact.
Why use it?
It helps distinguish exploitable security problems from theoretical or unreachable ones, so teams can judge severity and prioritize fixes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

exploitability-analyzer scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Exploitability Analyzer

Assess whether detected vulnerabilities are realistically exploitable.

Overview

This skill analyzes security vulnerabilities to determine if they're actually exploitable in practice. It examines control flow to assess reachability, traces input sources to evaluate controllability, analyzes sanitization logic, and considers execution context to provide realistic exploitability assessments with severity ratings.

How to Use

Provide:

  1. Vulnerable code: The code containing the vulnerability
  2. Vulnerability type: SQL injection, XSS, command injection, etc.
  3. Context: Surrounding code, input sources, sanitization functions
  4. Environment (optional): Execution privileges, security controls

The skill will analyze:

  • Reachability: Can attackers reach the vulnerable code?
  • Controllability: Can attackers control the vulnerable input?
  • Sanitization: Is input properly sanitized?
  • Impact: What damage can be caused?
  • Exploitability: Overall assessment (Critical/High/Medium/Low/None)

Analysis Workflow

Step 1: Identify Vulnerability Type

Classify the vulnerability:

  • SQL Injection
  • Command Injection
  • Cross-Site Scripting (XSS)
  • Path Traversal
  • LDAP Injection
  • Other injection types

Step 2: Trace Data Flow

Follow the data from source to sink:

Source: Where does the input originate?

  • User input (query params, POST data, headers)
  • Database values (second-order injection)
  • Configuration files
  • Environment variables
  • Hardcoded values

Transformations: What happens to the input?

  • Validation checks
  • Sanitization functions
  • Encoding/escaping
  • String operations

Sink: Where is the input used dangerously?

  • SQL query execution
  • System command execution
  • HTML rendering
  • File system operations

Step 3: Assess Reachability

Question: Can an attacker reach the vulnerable code path?

Critical: Public endpoint, no authentication High: Authenticated endpoint, common user role Medium: Requires specific conditions or privileges Low: Admin-only, internal function, rare code path None: Dead code, unreachable

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

exploitability-analyzer is a skill published in the GitHub repository ArabelaTso/Skills-4-SE (252 stars, last pushed 22d ago), licensed Apache-2.0. It adds 127 tokens to every session and 3,370 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
