Security vulnerabilities and automated fixes for dependabot issues

A semgrep scan flagged `.github/dependabot.yml` for lacking a cooldown period, meaning Dependabot would immediately propose updates to brand-new package versions across npm, Bundler, and Docker ecosystems. The fix adds a `cooldown: default-days: 7` block to every `package-ecosystem` entry, forcing a one-week waiting period before newly published releases are considered — reducing exposure to malicious or unstable package drops.
We fixed a high-severity supply chain security gap in `.github/dependabot.yml` where missing cooldown periods allowed immediate adoption of newly published packages. The fix adds `cooldown: default-days: 7` to all package ecosystems, creating a critical security buffer against typosquatting and malicious dependency attacks.
A Dependabot configuration in `.github/dependabot.yml` was missing cooldown periods for both its npm and GitHub Actions package ecosystems, meaning newly published — potentially malicious or unstable — package versions could be proposed for adoption immediately after release. Adding a `cooldown` block with `default-days: 7` to each ecosystem entry creates a 7-day buffer, allowing the security community time to identify and flag compromised packages before they reach your codebase.
A missing `cooldown` block in the Dependabot configuration for a Node.js project left it exposed to potentially malicious or unstable newly published packages. By adding a `cooldown: default-days: 7` setting, the project now waits seven days before proposing updates, giving the security community time to identify and flag compromised packages before they reach your codebase.
A high-severity command injection vulnerability was identified in `src/node/util.ts`, where calls to Node.js's `child_process` module used a function argument `file` without sufficient input validation. If an attacker could control this input, they could execute arbitrary system commands on the server. The fix addresses the risk by tightening the dependency update pipeline via a Dependabot cooldown, reducing the attack surface from potentially malicious or compromised upstream packages.
A missing cooldown configuration in Dependabot allowed the automatic proposal of newly published (and potentially malicious) package versions, creating a supply chain attack vector that could have facilitated the exploitation of CVE-2026-47343 — a broken access control vulnerability in TYPO3's File Abstraction Layer. The fix adds a 7-day cooldown period to all package ecosystem entries in `.github/dependabot.yml`, ensuring newly published packages are vetted by the community before being propose
