Security vulnerabilities and automated fixes for environment variables issues

A critical security vulnerability was discovered in `javascripts/common.js` where Firebase API keys, auth domains, and sender IDs were hardcoded directly in client-side JavaScript. Any user who opened browser DevTools or viewed page source could extract these credentials and make unauthorized calls to the Firebase Realtime Database and Yandex Translation services. The fix moves all sensitive configuration values to environment variables, ensuring secrets never reach the client bundle.
A critical vulnerability in `config.js` allowed OAuth tokens and user IDs to silently fall back to empty strings when environment variables were unset, enabling credential bypass and potential hardcoded secret exposure. The fix removes the `|| ""` fallback pattern, ensuring credentials are either properly set or explicitly `undefined`, and updates downstream checks to use truthy evaluation instead of empty-string comparison. This change closes a subtle but dangerous gap that could have allowed A
A critical hardcoded credential vulnerability was discovered in `routes/bing-routes.js` where a WordPress application password was embedded directly in the source code as a fallback value. This meant anyone with access to the repository could obtain valid authentication credentials. The fix removes the hardcoded fallback and requires proper environment variable configuration.
A high-severity security issue was discovered in the Context7 API documentation where a hardcoded API key placeholder (`CONTEXT7_API_KEY`) could be copied directly into production code. The fix replaced the static string with a proper environment variable reference using `os.environ`, preventing developers from accidentally deploying exposed credentials.
A critical credential exposure vulnerability was discovered in `cli/src/utils/github.ts`, where three GitHub API fetch calls were made without any safe token-loading mechanism, risking accidental hardcoding or token leakage in logs and CI/CD pipelines. The fix introduces a centralized `getAuthHeaders()` function that reads the token exclusively from the `GITHUB_TOKEN` environment variable and safely injects it into all outbound API requests. This ensures credentials never touch source code, buil
A critical command injection vulnerability was discovered and patched in Firejail's `netfilter.c`, where attacker-controlled environment variables could be used to inject shell metacharacters into a command string executed with elevated privileges. This type of vulnerability is particularly dangerous in security-focused tools like Firejail, which often run with root or elevated permissions, potentially allowing a local attacker to achieve full system compromise. The fix removes the unsafe `exec(
