chore: bump js-yaml and pm2

[dependabot]

Bumps js-yaml to 4.3.0 and updates ancestor dependency pm2. These dependencies need to be updated together.

Updates js-yaml from 4.1.1 to 4.3.0

Changelog

Sourced from js-yaml's changelog.

4.3.0, 3.15.0 - 2026-06-27

Security

• Backported maxTotalMergeKeys option.

[5.2.0] - 2026-06-26

Added

• Added maxTotalMergeKeys (10000) loader option to limit the total number of keys processed by YAML merge (<<) across one load() / loadAll() call.
• Added maxAliases (-1) loader option to limit the number of YAML aliases per document.

Removed

• maxMergeSeqLength replaced with maxTotalMergeKeys for limiting YAML merge processing.

Fixed

• Round-trip of integers with exponential form (>= 1e21)

[5.1.0] - 2026-06-23

Added

• Collection tags can finalize an incrementally populated carrier into a different result value.

Changed

• [breaking] quoteStyle now selects the preferred quote style; use the restored forceQuotes option to force quoting non-key strings.

[5.0.0] - 2026-06-20

Added

• Added named exports for schemas, tags, parser events and AST utilities.
• Reworked JSON_SCHEMA and CORE_SCHEMA with spec-compliant scalar resolution rules, and added YAML11_SCHEMA.
• Added realMapTag for lossless mappings with non-string and complex keys. Object-based mappings now reject complex keys instead of stringifying them.
• Added dump() transform option for changing the generated AST before rendering.
• Added dump() options seqInlineFirst, flowBracketPadding, flowSkipCommaSpace, flowSkipColonSpace, quoteFlowKeys, quoteStyle and tagBeforeAnchor.
• Added formal data layers (events and AST) for modular data pipelines.
  • Added low-level parser (to events), presenter and visitor APIs.
• Added the YAML Test Suite to the test set.

Changed

• See the migration guide for upgrade notes.
• Rewritten in TypeScript and reorganized the public API around flat named exports.

Updates pm2 from 6.0.14 to 7.0.3

Release notes

Sourced from pm2's releases.

v7.0.3

7.0.3

Bug Fixes

• Fix daemon failing to boot on Node.js < 14.18 — embedded vizion used node:-scheme requires; switched to bare specifiers

v7.0.2

7.0.2

Bug Fixes

• Fix pm2 serve returning 403 Forbidden on Windows — traversal guard used hardcoded / separator #6109
• Fix pm2 ls table misalignment when a username exceeds the user column width — cli-tableau's truncate() miscounts ANSI bytes, leaking bold into the watching column
• Fix long status lines (e.g. Applying action … on app […]) wrapping on narrow terminals — Common.printOut now ANSI-aware crops single-line TTY output to terminal width (piped output unaffected)

Features

• pm2 ls host-metrics line now shown by defaultpm2 update)
• pm2 ls adaptive layout: picks the widest layout that fits the terminal — full → condensed → new ultra-compact mini (id · name · status · cpu · mem) — and caps the name column so long names can't overflow the table
• pm2 ls host-metrics line only lists network interfaces carrying traffic (hides idle utun/awdl/bridge/anpi/unused en*)
• pm2 ls host-metrics line: replaced mem free with ram usage (%), added GPU memory/temperature when reported, per-interface network errors/drops shown when non-zero

Core Refactor

• Drop old vizion module, refactor to support only git and drop 3 submodules
• Replace the bundled pm2-sysmonit module and systeminformation with lib/tools/SysMetrics.js (Linux/macOS); pm2 slist/getSystemData and the Docker metrics path now read this collector. Covered by test/programmatic/sysmetrics.mocha.js

Security

• Bump js-yaml 4.1.1 → 4.3.0 — fixes quadratic-complexity DoS in merge-key handling (GHSA-h67p-54hq-rp68) #6122
• Bump ws 8.20.0 → 8.21.0 — fixes uninitialized-memory disclosure and tiny-fragment DoS (GHSA-58qx-3vcg-4xpx, GHSA-96hv-2xvq-fx4p) #6116
• Bump @pm2/js-api 0.8.0 → 0.8.1, pulling in patched ws@8.21.0 (its transitive ws was pinned to the vulnerable 7.x). Production deps are now advisory-free (npm audit --omit=dev clean)

v7.0.1

7.0.1

Bug Fixes

• Fix Python (and other non-Node) interpreter regression on Ubuntu: bun runtime detection used a naive includes('bun') substring check that matched any path containing the letters "bun" — most notably /home/ubuntu/.... Affected paths were routed through ProcessContainerForkBun.js and crashed with SyntaxError: unterminated string literal when Python tried to parse the JS container. Anchored the match to the end of the interpreter path (=== 'bun' or /bun$/) in both lib/God/ForkMode.js and lib/Common.js #5990
• Display max_memory_restart in pm2 describe output when set #5925
• Add missing port option to StartOptions TypeScript declaration #6045
• Fix incorrect file permissions on openrc.tpl template (0755 → 0644) #5957
• Fix Windows cmd.exe regression: revert bin/pm2* launchers to #!/usr/bin/env node shebang (was polyglot #!/bin/sh). Polyglot worked on Linux/macOS but broke npm's pm2.cmd shim on Windows — cmd.exe can't interpret /bin/sh shebang and failed with '"/bin/sh"' is not recognized as an internal or external command. PowerShell's auto-generated pm2.ps1 shim happened to call node directly so it kept working, masking the regression. Bun-only Linux/macOS users (no Node installed) need to symlink node to bun (sudo ln -s $(which bun) /usr/local/bin/node) — same workaround used in the project's bun test Dockerfile. Documented in README #6108

🤖 Claude Dependabot Review

Safe to merge: Needs review
Version bump: js-yaml 4.1.1 → 4.3.0 (minor/security) + pm2 6.0.14 → 7.0.3 (major)
Breaking changes: pm2 has a major version bump (6 → 7); the @pm2/agent module was removed in pm2 7.x, which drops PM2 Plus / cloud monitoring agent support
Notable changes: js-yaml 4.3.0 backports a security fix (maxTotalMergeKeys option) to prevent YAML merge-key DoS attacks — this is the primary motivation for the update, and pm2 must be bumped alongside it since pm2 depends on js-yaml transitively
Recommendation: Review the pm2 7.x changelog for breaking changes before merging, especially if PM2 Plus cloud monitoring or any pm2 agent features are in use; the security fix in js-yaml makes this worth prioritizing.
