CVE-2020-6482Network attack vector

Navigation restriction bypass via DevTools policy failure

Published May 21, 2020 · Updated Aug 4, 2024

Insufficient DevTools policy enforcement in Google Chrome before 83.0.4103.61 allows attackers to bypass navigation restrictions. Public vendor materials do not disclose the specific DevTools locus or the incorrect policy decision made for crafted extension navigation. Exploitation requires convincing a user to install a malicious Chrome extension; the demonstrated consequence is navigation-policy bypass, not code execution.
