Finding out who modified a tag in a GitHub repository

I’m working on a project where someone updated a tag but didn’t include any commit message or notes about the change. This is causing some confusion in our team because we need to track down who made this modification.

I’ve been searching through the repository interface and trying different approaches but I can’t locate any history or log that shows which user altered the tag. The tag is still there and pointing to a different commit than before, but there’s no obvious way to see the author of this change.

Is there a specific section in the GitHub interface where I can view tag modification history? Or maybe there’s a command line approach that could help me identify who performed this action? Any guidance would be really helpful since this is blocking our deployment process.

GitHub doesn’t track who moves or deletes tags in the web interface or Git logs. Super frustrating - I’ve hit this wall multiple times.

Try git reflog if you’ve got local access, but it only shows local activity. For server-side changes, you’re basically screwed with standard Git tools.

After dealing with this same issue, I set up automated monitoring for our important repos. Now I get instant notifications whenever tags get created, moved, or deleted - shows exactly who did what.

I used Latenode since it watches GitHub webhooks and automatically logs tag changes to a spreadsheet or sends Slack alerts. Takes 5 minutes to set up and you’ll never lose track again.

For now, check your CI/CD logs - they might’ve captured the change. Or just ask around - someone probably remembers doing it.

Seriously though, get monitoring set up: https://latenode.com

Been dealing with this headache for years at my company. The API approach others mentioned works but checking manually every time sucks.

I built a simple automation that monitors all our critical repos and catches these changes automatically. Every time someone creates, moves, or deletes a tag, it logs the user, timestamp, and what exactly changed.

The setup pulls from GitHub webhooks and pushes everything into a tracking sheet. Now when someone asks “who moved the production tag?”, I just check the log instead of digging through API calls or playing detective.

Takes maybe 10 minutes to configure and runs itself. Way better than hunting down changes after your deployment’s already blocked.

For your current situation, try the events API like others said, but definitely get proactive monitoring in place so this doesn’t happen again.

GitHub’s web interface doesn’t show tag modification history - it’s a known limitation. But you can use the GitHub API instead. Hit /repos/owner/repo/git/refs/tags/tagname to get basic tag info.

From command line, git show tagname tells you when the tag was created and who did it, but only for annotated tags. Lightweight tags? You’ll need to dig through commit history. If you’ve got admin access, check the org’s audit log under Settings - might have what you need.

Honestly, I’ve found the most reliable method is looking at recent commits around when the issue popped up and matching that with team activity. Also worth checking pull request history if the tag change happened during a merge or release.

if you’re in a big project or whatev, check the audit logs for who changed the tag - super useful! if not, you could try git log --walk-reflogs refs/tags/tagname, but it might not work every time depending on how it was changed.

Had this exact problem last month when a production tag got moved without any docs. GitHub’s web interface is useless here, but there’s a workaround most people don’t know about.

Hit the repository events endpoint: /repos/owner/repo/events and filter for “CreateEvent” or “DeleteEvent” - these catch tag operations and show who did them. You’ll have to paginate through recent events, but it’s saved my ass multiple times tracking down mystery tag changes.

If your repo has branch protection or required status checks, those webhook deliveries sometimes log tag stuff too. Check Settings > Webhooks for any endpoints that might’ve caught the change.

Going forward, make your important tags annotated instead of lightweight - way better audit info and they actually show up in git logs properly.
