Microsoft · Internet Explorer

CVSS 4.3 EPSS 62% 3 public exploits Fix deadline passed 18 April 2022

What it is

Microsoft Internet Explorer allow remote attackers to obtain sensitive information from process memory via a crafted web site.

Why we say that

  • EPSS puts exploitation in the next 30 days at 62%
  • 3 public exploits published
  • CISA's federal remediation deadline (2022-04-18) 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.
