CVE-2026-62640Network attack vector

Unauthenticated takeover via undisclosed IIOP flaw

Published Aug 18, 2026 · Updated Aug 25, 2026

Authentication flaw in Oracle Reports Developer 14.1.2.0.0 allows remote attackers to take over the product through unauthenticated IIOP. Oracle identifies the Security and Authentication component but has not published the defective code path or operation on untrusted IIOP input. Network reachability of the IIOP service is sufficient; successful exploitation grants control affecting data confidentiality, integrity, and service availability.
