GitHub Actions Secrets: 8 Common Mistakes and Fixes
GitHub Actions provide a powerful way to automate tasks, but they also introduce the risk of secrets leakage if not managed properly. This article outlines eight common mistakes developers make when handling secrets in GitHub Actions and provides solutions to avoid these issues. Secrets in GitHub Actions include API keys, passwords, tokens, and webhook URLs.

Another common mistake is printing secrets in logs, which can be prevented by removing debug commands or printing whether a secret is empty. Trusting GitHub's log masking is also unreliable, so it's better to store each secret as a single value and use the `::add-mask` command to hide sensitive values.
Using overly powerful keys can lead to significant damage if leaked, so it's essential to grant the smallest permission required and use separate keys for each project. Using restricted keys for services like Bluesky bots can further enhance security.
