🚨 #Composer 2.9.8 & 2.2.28 are out with an urgent security fix: #GitHub Actions GITHUB_TOKEN and GitHub App installation tokens were being leaked in plain text to CI job logs. If you run #Composer in #GitHubActions — update immediately.
🔍 Root cause: Composer validates GitHub tokens against an allowed character set. When a token fails validation, the full token value was interpolated directly into the exception message — exposed on stderr and captured in CI logs.
