Google Chromium V8 Remote Code Execution Vulnerability

Google · Chromium V8

CVSS 8.8 EPSS 85% 1 public exploit Fix deadline passed 22 June 2022

What it is

Google Chromium V8 Engine contains an unspecified vulnerability that allows a remote attacker to execute code inside a sandbox via a crafted HTML page. This vulnerability could affect multiple web browsers that utilize Chromium, including, but not limited to, Google Chrome, Microsoft Edge, and Opera.

Why we say that

  • EPSS puts exploitation in the next 30 days at 85%
  • 1 public exploit published
  • CISA's federal remediation deadline (2022-06-22) has passed
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.

What to do

Apply updates per vendor instructions.

Public exploit code

Indexed from Exploit-DB. Presence of code raises urgency; absence does not mean safety.
