Security vulnerabilities and automated fixes for configuration security issues

The pet-window module constructed dynamic JavaScript by embedding raw configuration values into code strings. An attacker with local access could inject arbitrary JavaScript by modifying stored configuration. The fix replaces string interpolation with explicit Number() coercion and NaN validation for all numeric configuration parameters.
A hardcoded Google Maps API key was discovered in `exampleSite/config/_default/params.toml` at line 113, exposing a live credential that any attacker could extract from the repository and use to make unauthorized API calls. This critical vulnerability was automatically detected and fixed by replacing the hardcoded key with an empty placeholder, eliminating the risk of credential theft and unauthorized usage charges.
A critical misconfiguration in `platforms/m365/wrangler.toml` left developers one copy-paste away from committing live API keys directly into git history. The fix adds an explicit warning comment blocking the `[vars]` anti-pattern and adds `.dev.vars` to `.gitignore`, ensuring secrets flow through Cloudflare's encrypted `wrangler secret` mechanism instead of plaintext config. This matters because git history is permanent — a key committed even once can be extracted long after it's "deleted."
A critical security issue was discovered in the S3 Express deployment configuration file where an AWS Secret Access Key was hardcoded as a placeholder example. This vulnerability could allow attackers to gain unauthorized access to AWS resources if the example file was accidentally deployed to production or committed to version control without proper sanitization.
A hardcoded AWS Secret Access Key pattern was detected in the `settings.example` configuration file of an nginx AWS credentials module. While the value itself was a placeholder string, its format matched a real AWS secret key pattern, making it a dangerous template that could mislead developers into committing real credentials. The fix replaces the lookalike secret value with an unambiguous placeholder that cannot be mistaken for or used as a real credential.
