What happened
CISA added CVE-2026-21962 (CVSS 10.0), an unauthenticated improper access control flaw in Oracle HTTP Server and Oracle WebLogic Server Proxy Plug-in, to its Known Exploited Vulnerabilities catalog due to active exploitation. Oracle patched the flaw in January 2026, but GreyNoise and CloudSEK reported exploitation attempts as recently as March 2026, including against honeypots, alongside older WebLogic RCE flaws like CVE-2020-14882.
Why it matters
Only relevant if you operate Oracle WebLogic or Oracle HTTP Server with the Proxy Plug-in in your stack; if so, confirm the January 2026 patch is applied immediately since active exploitation is confirmed. For the majority of this audience not running WebLogic, no action is needed.
Discussion angle
Briefly note this as a CVSS 10.0 actively-exploited flaw, but focus the segment on why most attendees can skip it—WebLogic is niche for modern SaaS/AI stacks—and use it as a quick example of how KEV catalog additions signal real-world exploitation, not just theoretical risk.
