✓ Safe to upgrade

I recommend merging this upgrade because js-yaml is only used as a dev dependency (likely for Cypress testing configuration) with no direct code imports found in the codebase. The upgrade patches a prototype pollution security vulnerability while maintaining full backward compatibility with no breaking changes. The security fix strengthens protection against proto key manipulation attacks.

What we checked

• js-yaml declared as devDependency only (not production dependency), limiting exposure ^[1]
• Upgrade from 4.1.0 to 4.1.1 - patch version with security fix for prototype pollution (GHSA-mh29-5h37-fv8m) ^[2]
• Searched for 'js-yaml', 'jsyaml', require/import statements, and yaml.load/dump usage patterns across all .js/.jsx/.ts files - no direct usage found in application code ^[3]

Changes

js-yaml upgraded with a critical security fix that blocks prototype pollution attacks by preventing proto key manipulation in the YAML merge operator. The update strengthens object construction safeguards across both mergeObjects() and constructMapping() functions.

• Enhanced prototype pollution protection by extracting setProperty() helper function and applying it consistently in both mergeObjects() and constructMapping() to prevent proto key manipulation (v4.1.1, other)
• Fix prototype pollution issue in yaml merge (<<) operator. (v4.1.1, changelog)
• Updated documentation URLs from HTTP to HTTPS for yaml.org and pyyaml.org references in README (v4.1.1, other)

View 3 more changes

• Updated demo link from http://nodeca.github.com/js-yaml/ to https://nodeca.github.io/js-yaml/ in README (v4.1.1, other)
• Added documentation for 'empty' style option for !!null type (serializes null values as empty string) (v4.1.1, other)
• Removed CHANGELOG.md file from package distribution (v4.1.1, other)
