The project has been abandoned.
HOW TO TELL
No release in a year or more The project site is unchanged or gone Security issues reported and unaddressed The community has moved elsewhere
WHY IT MATTERS
No security fixes. Vulnerabilities discovered after abandonment are never patched, and automated scanners eventually find them.
This is a question of when, not whether.
WHAT TO DO
Establish whether a maintained fork exists, which is common for popular abandoned projects Plan a migration to a maintained alternative In the interim, reduce exposure: restrict access, remove unnecessary features, monitor closely
WHAT NOT TO DO
Continue indefinitely and hope. The cost of a compromise exceeds the cost of migrating.
PLANNING THE MIGRATION
Export your content while the application still works Identify a maintained alternative Test it properly before committing Preserve URLs and redirects
THE HONEST TIMING
Migrate before it becomes urgent. Doing it after a compromise is the same work under worse conditions.
