chore(deps): bump the npm_and_yarn group across 1 directory with 2 updates

[dependabot]

Bumps the npm_and_yarn group with 2 updates in the /apps/sim directory: js-yaml and nodemailer.

Updates js-yaml from 4.1.1 to 4.2.0

Changelog

Sourced from js-yaml's changelog.

[4.2.0] - 2026-06-01

Added

• Added docs/safety.md with notes about processing untrusted YAML.
• Added maxDepth (100) loader option. Not a problem, but gives a better exception instead of RangeError on stack overflow.
• Added maxMergeSeqLength (20) loader option. Not a problem after merge fix, but an additional restriction for safety.
• Added sourcemaps to dist/ builds.

Changed

• Stop resolving numbers with underscores as numeric scalars, #627.
• Switched dev toolchains to Vite / neostandard.
• Updated demo.
• Reorganized tests.
• dist/ files are no longer kept in the repository.

Fixed

• Fix parsing of properties on the first implicit block mapping key, #62.
• Fix trailing whitespace handling when folding flow scalar lines, #307.
• Reject top-level block scalars without content indentation, #280.
• Ensure numbers survive round-trip, #737.
• Fix test coverage for issue #221.
• Fix flow scalar trailing whitespace folding, #307.
• Fix digits in YAML named tag handles.

Security

• Fix potential DoS via quadratic complexity in merge - deduplicate repeated elements (makes sense for malformed files > 10K).

[3.14.2] - 2025-11-15

Security

• Backported v4.1.1 fix to v3

PR Summary

Low Risk
Version-only dependency bumps with security and hardening fixes; no logic changes, though YAML parsing and outbound email behavior may shift slightly on edge cases.

Overview
Bumps js-yaml from 4.1.1 to 4.2.0 and nodemailer from 8.0.7 to 8.0.9 in apps/sim/package.json only—no application code changes.

js-yaml is used for YAML file parsing and chunking; 4.2.0 adds loader safety limits (maxDepth, maxMergeSeqLength) and fixes a merge-related DoS issue, plus stricter parsing behavior that could affect edge-case YAML inputs.

nodemailer backs SMTP workflow sends and core email providers (SMTP/SES); 8.0.8–8.0.9 include TLS hardening for OAuth2/Ethereal, SMTP pool leak fixes, and patches for jsonTransport access bypass and List-* CRLF injection.

Greptile Summary

This PR bumps two npm dependencies in apps/sim/package.json: js-yaml from 4.1.1 to 4.2.0 and nodemailer from 8.0.7 to 8.0.9, both of which carry security-relevant fixes.

• js-yaml 4.2.0: Fixes a potential DoS via quadratic complexity in YAML merge handling, adds maxDepth (100) and maxMergeSeqLength (20) loader options as safety limits, and fixes several parsing edge cases.
• nodemailer 8.0.9: Addresses two pending security advisories (jsonTransport access bypass and List-* CRLF injection), enforces strict TLS for OAuth2/Ethereal credential requests, and fixes four listener/stream leaks in the SMTP transport.

Confidence Score: 5/5

Safe to merge — two dependency version bumps that close known security vulnerabilities with no breaking API changes.

Both updates are patch/minor bumps from reputable libraries fixing documented security issues. The changes are isolated to version strings in package.json, and neither library has breaking API changes in these ranges. The nodemailer update closes active security advisories (CRLF injection, access bypass), making merging this promptly preferable to deferring.

No files require special attention.
