PII data in Git isn’t just a leak risk. It’s a compliance threat. Once committed, it lives in the repo’s full history, replicated across clones, backups, forks. Even if you remove it in the latest commit, it lingers in past versions until you rewrite history.
This is where git rebase becomes more than a tool for tidying commits. With an interactive rebase, you can surgically edit or drop commits containing PII. Combined with git filter-repo or BFG Repo-Cleaner, it lets you purge sensitive data from every reachable commit before pushing again.
Steps to remove PII data using Git rebase:
- Identify commits containing PII. Use
git log -p or search with git grep. - Start an interactive rebase:
git rebase -i <commit-hash>^. - Change
pick to edit for offending commits. - Remove the PII from files.
- Amend the commit with
git commit --amend. - Continue the rebase, then force-push to overwrite remote history.
Always confirm the cleanup worked by scanning the repo with automated detection tools. PII removal without verification is a false sense of security. After rewriting history, lock down processes to prevent sensitive data from being committed again.
Git rebase with PII data cleanup is high-stakes surgery. It must be precise, fast, and complete—because anything left behind is still exposed. Tools like hoop.dev let you monitor code for PII before it ever lands in Git. Catch it early. Remove it cleanly.
