Why it Matters

Some Magento extensions may still function but the vendor has stopped providing support — no security advisories, no patch releases, and no response to issues. Using unsupported extensions leaves the store vulnerable because any new vulnerabilities will remain unpatched forever.

Flagging extensions with no vendor support ensures store owners can plan to replace or remove them before they become long-term security liabilities.

Verification Steps

# Review vendor communication channels:
# - Marketplace listing "last updated"
# - GitHub repository commits, releases, issues
# - Vendor website or support portal

# Expected: Active vendors show recent updates and support responses.
# No activity for 12+ months = unsupported.

composer show vendor/extension -a
# Check "abandoned" flag or lack of recent releases

Remediation / Fix Guidance

1. Maintain an inventory of installed extensions with vendor info and last update date.
2. If an extension is unsupported:
   • Plan migration to a maintained alternative.
   • Consider removing the feature entirely if not business-critical.
   • If unavoidable, fork the code and maintain security patches internally.
3. Update procurement policies to forbid installing extensions without active vendor support.

Examples

# Marketplace listing: last updated 2021
# GitHub repo inactive, vendor site offline
# Extension still running in production → FAIL

# Marketplace listing: updated Jan 2025
# Vendor actively responding to issues and releasing patches
# Safe to continue using → PASS
