What it is

Oracle Fusion Middleware contains an unspecified vulnerability in the WLS Core Components that allows an unauthenticated attacker with network access via IIOP to compromise the WebLogic Server.

Why we say that

  • EPSS puts exploitation in the next 30 days at 93%
  • CISA's federal remediation deadline (2023-12-07) has passed
  • CVSS 9.8 critical
  • 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 mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
