Preface: Google Chrome comes with DevTools built directly into the browser by default. These are a comprehensive set of web developer tools that allow users to inspect and debug web pages, analyze network activity, monitor performance, and much more.
You can use the snippets option available in the Sources tab in Chrome DevTools. Just type out your code as you do in a code editor and hit Ctrl+Enter (or click on the Run snippet button available there) to execute the code, and the output displays in the console at the bottom.
Background: In Chrome DevTools, “Copy as cURL” is a feature in the Network panel that lets you right-click on a network request and copy it as a curl command. This command replicates the HTTP request outside the browser, including:
- URL
- HTTP method (GET, POST, etc.)
- Headers (cookies, authorization tokens, etc.)
- Payload (for POST/PUT requests)
Vulnerability details: Insufficient validation of untrusted input in Devtools in Google Chrome prior to 140.0.7339.80 allowed a remote attacker to execute arbitrary code via user action in Devtools. (Chromium security severity: Low)
This CVE refers to a design flaw in Chrome DevTools that could allow unauthorized access or privilege escalation under certain conditions. Based on the advisory, the flaw likely involves:
- Improper isolation or authentication when DevTools is exposed.
- Attackers exploiting CDP endpoints without proper permission checks.
Best-Practice Checklist
- Always update to Chrome ≥ 140[.]0[.]7339[.]80.
- Launch with
--remote-debugging-portand--user-data-dir(non-default). - Avoid exposing the CDP port; use localhost only or protected proxies like devtoolium.
- Audit DevTools features (e.g., “Copy as cURL”) before exposing them via CDP.
- For automation, consider Chrome for Testing for safer, isolated CDP usage.
