Chromium Security

The Chromium security team aims to provide Chrome and Chrome OS users with the most secure platform to navigate the web, and just generally make the Internet a safer place to hang out. We work on solutions for the biggest user / ux security problems, drive secure architecture design and implementation projects for the Chromium platform, find and help fix security bugs, help developers to create more secure apps, and act as a general security consulting / review group for the larger Chromium project.

How can I get involved?

Find bugs

One of the quickest ways to get involved is finding and reporting security bugs. It will get prompt attention from a security sheriff, be kept private until we coordinate disclosure, and possibly qualify for a cash reward through our Vulnerability Rewards Program. We occasionally run security contests outside of our regular reward program (e.g. Pwnium2, Pwnium3) too.

For any issues other than a specific bug, email us at For non-confidential discussions, please post to the technical discussion forums, including the public security-dev list for technical discussions.

Become a committer

We encourage interested parties to work towards becoming a committer. There are many types of security related patch that we're excited to collaborate on:

Become an IPC reviewer

Bugs in IPC can have nasty consequences, so we take special care to make sure additions or changes to IPC avoid common security pitfalls. If you want to get involved, check out how to become an IPC reviewer here.

How can I get access to Chromium vulnerabilities?

A history of fixed Chromium security bugs is best found via security notes in Stable Channel updates on the Google Chrome releases blog. You can also find fixed, publicly visible Type=Bug-Security bugs in the issue tracker (note: security bugs automatically become publicly visible 14 weeks after they are fixed). All security bugs are rated according to our severity guidelines, which we keep in line with industry standards.

Advance notice of (fixed) Chromium security vulnerabilities is restricted to those actively building significantly deployed products based upon Chromium, or including Chromium as part of bundled software distributions. If you meet the criteria, and require advanced notice of vulnerabilities, request access via Your email should explain your need for access (embedder, Linux distribution, etc.) and your continued access will require that you follow the terms of list membership.
