Oracle HTTP Server CVE-2026-21962: CVSS 10 Flaw in KEV
If an Oracle HTTP Server, Apache or IIS front end with the WebLogic proxy plug-in still lacks the January 2026 CPU, patch it now; exploit code has been public since January and the bug is now confirmed exploited.
Must act: Anyone running Oracle HTTP Server or the WebLogic Server Proxy Plug-in 12.2.1.4.0, 14.1.1.0.0 or 14.1.2.0.0 in front of WebLogic, most urgently on internet-facing or DMZ hosts.
Can relax: Sites that applied the January 2026 or a later Critical Patch Update to these components, and WebLogic deployments with no OHS, Apache or IIS proxy plug-in in front of them.
- Inventory every Oracle HTTP Server, Apache and IIS host that loads the WebLogic proxy plug-in, and record its version and applied patches.
- Apply the January 2026 CPU patches for Oracle HTTP Server and the WebLogic Server Proxy Plug-in (or a later CPU), starting with internet-facing and DMZ hosts.
- Patch the IIS plug-in separately; it is a different binary from the Apache/OHS module.
