CVE-2021-21137

Inappropriate implementation in DevTools in Google Chrome prior to 88.0.4324.96 allowed a remote attacker to obtain potentially sensitive information from disk via a crafted HTML page.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
