The version specifier has been changed from "latest" to a specific version "4.22.1". While this is good for security and reproducibility, it's inconsistent with other dependencies in this file. The "cheerio" dependency still uses "latest" as its version specifier. Consider changing "cheerio" to use a specific version as well for consistency and to avoid unexpected breaking changes in the future.

Suggested change
"cheerio": "latest"
"cheerio": "1.0.0-rc.12"

The PR description states the recommended version 4.22.1 was released on "2025-12-01" which is described as "2 months ago". However, version 4.22.1 appears to be the latest stable version which reverted a breaking change from 4.22.0. According to the release notes, CVE-2024-51999 referenced in version 4.22.0 has been rejected, meaning there was no actual security vulnerability. This version is appropriate to upgrade to, but the security justification for urgency may be overstated since the specific CVE was rejected.
