🦉 Allocation of Resources Without Limits or Throttling

Note

Low Risk
Dependency-only patch-level upgrade to express/transitive deps; low functional risk, primarily limited to potential minor behavior changes in the HTTP stack.

Overview
Updates the samples/js-chatbot/server dependency on express from ^4.21.0 (lockfile 4.21.2) to ^4.22.0.

The lockfile changes refresh Express’s dependency ranges and pull in qs@6.14.2 under Express (via ~6.14.0), aligning with the security fix; no application code changes.

Summary by cubic

Upgrade Express to 4.22.0 in the js-chatbot server to patch the qs vulnerability and improve security. No app code changes; upgrade is non-breaking.

Dependencies
- express: ^4.22.0 (was ^4.21.0); lockfile 4.21.2 → 4.22.0
- Pulls qs 6.14.2 under express, fixing SNYK-JS-QS-15268416 (resource allocation without limits)

Pinned Express version includes reverted regression

Medium Severity

package-lock.json now pins express to 4.22.0, a release with a known query-parser behavior regression that was reverted in 4.22.1. Environments using npm ci will consistently install the regressed version, which can change req.query parsing behavior and break routes relying on extended query parsing.

+        "body-parser": "~1.20.3",
+        "content-disposition": "~0.5.4",
        "content-type": "~1.0.4",

-        "cookie-signature": "1.0.6",
+        "cookie": "~0.7.1",
+        "cookie-signature": "~1.0.6",


This upgrade introduces Express 4.22.0 (which uses qs ~6.14.x), but the lockfile still installs qs@6.13.0 via body-parser@1.20.3 (see node_modules/body-parser -> qs: 6.13.0 and node_modules/qs@6.13.0). That means the qs vulnerability called out in the PR description may still be present. Consider updating the dependency chain so qs resolves to >=6.14.0 everywhere (e.g., add an npm overrides entry for qs or bump the transitive dependency that pins qs 6.13.0), then regenerate package-lock.json.
