[Snyk] Security upgrade @actions/core from 1.10.1 to 2.0.0

[revan-zhang]

Snyk has created this PR to fix 4 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• slack-notify-webhook/package.json
• slack-notify-webhook/yarn.lock

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

Vulnerabilities that will be fixed with an upgrade:

	Issue	Score
	Improper Handling of Highly Compressed Data (Data Amplification) SNYK-JS-UNDICI-15518068	710
	Uncaught Exception SNYK-JS-UNDICI-15518070	710
	HTTP Request Smuggling SNYK-JS-UNDICI-15518061	620
	CRLF Injection SNYK-JS-UNDICI-15518072	455

Note

Medium Risk
Medium risk because this is a major-version upgrade of @actions/core that changes transitive dependencies (@actions/http-client, undici) and could affect runtime behavior of the GitHub Action despite no code changes.

Overview
Upgrades the GitHub Action dependency @actions/core from ^1.10.1 to ^2.0.0.

Refreshes yarn.lock accordingly, introducing new transitive packages (e.g., @actions/exec, @actions/io) and bumping @actions/http-client/undici to newer major versions to remediate security issues.

🔴 dist/index.js not rebuilt after @actions/core major version bump — security fix has no effect

The package.json bumps @actions/core from ^1.10.1 to ^2.0.0 (intended as a vulnerability fix), but the bundled dist/index.js was not rebuilt. Since action.yml:30 specifies main: 'dist/index.js', GitHub Actions runs the bundled file, which still contains the old @actions/core v1.x code. The vulnerability fix therefore has no runtime effect — the action continues to use the old, vulnerable dependencies (undici@^5.25.4, @actions/http-client@^2.0.1). Additionally, slack-notify-webhook is not listed in the repo's build.sh, so automated builds won't pick it up either.

Prompt for agents

After updating the dependency in slack-notify-webhook/package.json, you need to rebuild the dist bundle so the fix actually takes effect at runtime. Run the following from the slack-notify-webhook directory:

yarn install
yarn build

This executes `ncc build src/index.js -m -o ./dist/` (as defined in package.json scripts) and produces an updated dist/index.js that bundles the new @actions/core v2 and its transitive dependencies.

Also consider adding slack-notify-webhook to the repo-level build.sh so future builds are automated. The build.sh at the repo root currently does not include slack-notify-webhook in its array of folders to build.
