Add SECURITY.md with vulnerability disclosure policy

[MD-Mushfiqur123]

Closes #6

[juanmanueldaza]

Changes Requested — Copy-Paste from linkedin2md

Two issues:

1. Scope creep: This PR bundles all code changes from PRs #21, #22, #23 alongside the SECURITY.md. Keep only SECURITY.md.

2. Wrong content: SECURITY.md lists "ZIP bomb or resource exhaustion" as a security concern, but github2md does not process ZIP files. This section was copy-pasted from linkedin2md, which does process LinkedIn data exports (ZIP files). For github2md, the relevant concerns are API rate limiting, gh CLI token exposure, and REST API path injection.

Please remove all code changes and rewrite the "What We Consider Security Issues" section to reflect github2md's actual attack surface, not linkedin2md's.

Hi @MD-Mushfiqur123 — following up on this PR. Two things still needed:

1. Remove all code changes (keep only SECURITY.md)
2. Rewrite the security concerns section — github2md doesn't process ZIP files like linkedin2md does. The relevant concerns are API rate limiting, gh CLI token exposure, and REST API path injection.

Let me know if you have questions!

[MD-Mushfiqur123]

Addressed: Rebased to include ONLY SECURITY.md. All unrelated code changes have been stripped. @juanmanueldaza please re-review.

Review Summary

Verdict: Changes Requested — one remaining item from the original review.

What was fixed ✅

• Scope creep resolved — now contains ONLY SECURITY.md. Clean.

Still needed 🔴

• Security concerns section is still copy-pasted from linkedin2md. github2md does not process ZIP files, so "ZIP bomb or resource exhaustion vulnerabilities" is irrelevant. The original review asked to rewrite this section for github2md's actual attack surface:
  • GitHub API rate limiting / token exposure (gh CLI tokens, REST API calls)
  • Path traversal in output file paths
  • Markdown injection via user-controlled content
  • Sensitive data in exported content

Lens	Score	Notes
DRY	10/10	Single file
KISS	10/10	Straightforward policy doc
YAGNI	10/10	Closes #6
OWASP	7/10	Content misaligned with project's actual attack surface

Once the concerns section is rewritten for github2md, good to merge.

🔴 "ZIP bomb or resource exhaustion vulnerabilities" — github2md doesn't process ZIP files (that's linkedin2md's domain). Replace with: GitHub API rate limiting / token exposure, and/or REST API path injection.

PR #25 Review: Changes Requested

Good work on the SECURITY.md content itself — it covers the right scope. However, same issue as PR #27: the branch is based on an old commit and carries unintended changes.

Problem: Still based on old commit

This branch (84cb653) is behind current main and includes:

• Deleting .github/CODEOWNERS — added in PR #24, not related to SECURITY.md.
• Removing README badges — not related.
• Changing GA4 measurement ID — unexplained, not related.

What to do

1. Rebase on current main
2. Keep only SECURITY.md — the diff should be a single new file. Remove all changes to docs/index.html, .github/CODEOWNERS, and README.md.

Once rebased and scoped cleanly to just the new SECURITY.md file, this is ready to merge. The content itself is solid.

Clean SECURITY.md, no scope creep. Well-structured — covers path traversal, injection, ZIP bombs, and has responsible disclosure. LGTM. 🚀
