vulnerability-scanner

A vulnerability-scanning skill that checks software packages, dependencies, operating-system packages, Docker images, exposed services, and software versions for known security weaknesses. A CVE is a public identifier for a specific vulnerability.

In plain words
What is it for?
Use it to identify versions, look up relevant CVEs and security advisories, scan container images, and report affected versions, fixes, and recommended updates.
Why use it?
It connects installed versions to current vulnerability records and produces severity and remediation information.

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 D, and why

vulnerability-scanner scanned grade D with 3 findings 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 2d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

The opening of the file, as written. The whole thing — 244 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vulnerability Scanner

CVE research, system package auditing, and container image vulnerability scanning. Uses web search for CVE lookups and local tools for package/image analysis.

Quick Start

Quick CVE Check for a Specific Software

  1. Identify the software and version
  2. Web search: "[software name] [version] CVE site:nvd.nist.gov OR site:github.com/advisories"
  3. Assess: Is the target version affected?
  4. Report: Severity, affected versions, fix version, remediation steps

CVE Web Search Workflow

Step 1: Identify Software Versions

Gather current versions of monitored software:

# Docker
docker --version
docker compose version

# System packages (Arch Linux)
pacman -Q <package-name>

# Pi-hole (via SSH or API)
# Check ../workspace-devops/MEMORY.md for known version

# Gitea (via web UI or API)
curl -s http://<gitea-host>:3000/api/v1/version

Step 2: Search for CVEs

Use web search with targeted queries:

Software Search Query
Pi-hole "Pi-hole" CVE 2025 2026 vulnerability
Gitea "Gitea" CVE 2025 2026 security advisory
Docker "Docker Engine" CVE 29.2 vulnerability
Ollama "Ollama" CVE vulnerability security
OpenClaw "OpenClaw" CVE vulnerability security

Useful sources:

  • NVD: site:nvd.nist.gov
  • GitHub Advisories: site:github.com/advisories
  • MITRE: site:cve.mitre.org
  • Vendor security pages (e.g., blog.gitea.com/security)

Step 3: Assess Impact

For each CVE found:

Field Description
CVE ID e.g., CVE-2026-XXXXX
CVSS Score 0.0 - 10.0
Severity Critical / High / Medium / Low
Affected versions Which versions are vulnerable
Target version What is running
Exploitability Is there a public exploit?
Impact What can an attacker do?
Fix version Which version patches this?
Mitigation Workaround if upgrade isn't immediate

Step 4: Report

Update MEMORY.md:

  • Add to Known Vulnerabilities table if affected
  • Update CVE Watch List with last check date
  • Log in Audit History

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.

vulnerability-scanner is a skill published in the GitHub repository Firstp1ck/pi-coding-agent-forge (74 stars, last pushed 3d ago), licensed MIT. It adds 43 tokens to every session and 1,492 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
