Technical details
This is an easily exploitable vulnerability in the Oracle XML Gateway Install component affecting versions 12.2.3–12.2.15. The vulnerability allows a low-privileged, network-accessible attacker (via HTTP) to bypass authorization controls and access restricted data or cause partial denial of service. The attack requires valid authentication (PR:L) but no user interaction. Successful exploitation results in high confidentiality impact (unauthorized access to critical and all accessible data) and low availability impact (partial DoS). A patch is available via Oracle's September 2026 Critical Patch Update.
