Oracle · WebLogic Server

CVSS 9.8 EPSS 95% no public exploit indexed Fix deadline passed 28 January 2025

What it is

Oracle WebLogic Server, a product within the Fusion Middleware suite, contains an unspecified vulnerability exploitable by an unauthenticated attacker with network access via IIOP or T3.

Why we say that

  • EPSS puts exploitation in the next 30 days at 95%
  • CISA's federal remediation deadline (2025-01-28) 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.
