Merge Risk: Medium

This minor version upgrade for js-yaml introduces security enhancements and bug fixes. While not containing major API changes, one change introduces a new default that could affect specific use cases.

Key Changes:

  • New maxDepth Loader Option: Version 4.2.0 introduced a maxDepth option to the loader, which defaults to 100. This is a security hardening measure to prevent Denial of Service (DoS) attacks caused by deeply nested YAML documents. [1]
  • Security Fixes: The upgrade to 4.3.0 and higher resolves vulnerabilities related to inefficient algorithmic complexity in merge key (<<) handling, which could also lead to DoS. [5]

Potential Impact:

  • The maxDepth default could cause errors in applications that legitimately process YAML files with a nesting depth greater than 100. Previously, these would have been parsed without error (though potentially causing performance issues).

Recommendation:
Verify if your application processes YAML documents with a nesting depth exceeding 100. If so, you may need to explicitly configure the maxDepth loader option to a higher value to avoid new errors.
