Security vulnerabilities and automated fixes for yaml issues

A high-severity configuration vulnerability was discovered in a `.github/dependabot.yml` file that lacked a cooldown period for package updates. Without this safeguard, Dependabot could immediately propose updates to newly published package versions—including potentially malicious or unstable releases. The fix adds a simple `cooldown` block with a 7-day waiting period before any new package version is suggested.
A high-severity configuration gap was discovered in a Node.js library's `.github/dependabot.yml` file where no cooldown period was set for dependency updates. This meant Dependabot could immediately propose updates to newly published (and potentially malicious) package versions, exposing the project and all downstream consumers to supply chain attacks. The fix adds a `cooldown` block with `default-days: 7` to both the `npm` and `github-actions` package ecosystem entries.
A high-severity supply chain vulnerability was discovered in a `.github/dependabot.yml` configuration that lacked a cooldown period, meaning Dependabot could immediately propose updates to newly published (and potentially malicious) package versions. The fix adds a `cooldown` block with `default-days: 7` to enforce a 7-day waiting period before suggesting updates, giving the community time to detect and flag compromised packages.
A high-severity supply chain vulnerability was discovered in a Dependabot configuration file that lacked cooldown periods for package updates. Without cooldown settings, Dependabot could propose updates to newly published—and potentially malicious—packages immediately after release. The fix adds a 7-day cooldown period to all three package ecosystems (npm, GitHub Actions, and Maven), giving the community time to identify compromised packages before they're automatically proposed.
A high-severity supply chain vulnerability was discovered in a `.github/dependabot.yml` configuration file that lacked a cooldown period for package updates. Without a cooldown, Dependabot could immediately propose updates to newly published—and potentially malicious—package versions. The fix adds a 7-day `cooldown` block to both the npm and github-actions ecosystem entries, giving the community time to identify and flag compromised packages before they're adopted.
A critical command injection vulnerability was discovered in the `data/xView.yaml` dataset download script, where `os.system(f'rm -rf {labels}')` constructed a shell command using an f-string with a path derived from user-controlled YAML configuration. An attacker supplying a crafted dataset YAML file could embed shell metacharacters in the path to execute arbitrary commands. The fix replaces the shell invocation entirely with Python's `shutil.rmtree()`, eliminating the attack surface by never i
A high-severity shell injection vulnerability was discovered and fixed in a GitHub Actions deployment workflow, where direct use of `${{github.*}}` context variables in `run:` steps could allow attackers to execute arbitrary code in the CI/CD runner. This type of attack can lead to secret theft, source code exfiltration, and complete pipeline compromise. The fix involves routing untrusted context data through intermediate environment variables before using them in shell scripts.
