Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Insufficient policy enforcement in navigations in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to bypass content security policy via a crafted HTML page.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A content security policy (CSP) bypass vulnerability in Google Chrome's navigation handling allowed remote attackers to circumvent CSP protections via specially crafted HTML pages. The insufficient policy enforcement in navigation processes permitted malicious pages to bypass intended security restrictions.

MitigationUpdate Google Chrome to version 77.0.3865.75 or later. Organizations should ensure end-users have updated browsers and may consider deploying automated update mechanisms or browser management policies.
