hunt-lfi
Hunt Local File Inclusion (LFI), Remote File Inclusion (RFI), and Path Traversal — /etc/passwd read, log poisoning → RCE, PHP filter-chain RCE (no upload needed), php:// / data:// / zip:// / phar:// wrappers, RFI via allow_url_include, directory traversal read/write/delete. Covers OOB/blind LFI confirmation and false-positive discipline. Use when hunting file-include or path-traversal bugs on any target.

Security
3 findings: 2 critical severity, 1 high severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
Multiple URLs are attacker-controlled "shell" endpoints and OOB callback placeholders (remote include targets) used to host/trigger PHP shells or exfiltrate data — these are high-risk RFI/LFI artifacts; the GitHub repo shown is a known security tool (benign).
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This document is an explicit, actionable offensive guide describing techniques to read sensitive files, exfiltrate credentials, and achieve remote code execution (filter-chain RCE, RFI, log/session poisoning), i.e. clear malicious/backdoor-capable behavior.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill explicitly instructs reading and "report[ing] exactly what you recovered" from sensitive files (e.g., .env, ~/.aws/credentials) and shows OOB/exfiltration payloads, which requires the agent to include recovered secret values verbatim in outputs.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill instructs at runtime to fetch and execute remote code via "git clone https://github.com/synacktiv/php_filter_chain_generator" followed by running the downloaded Python script, which clearly pulls external code that is then executed.
