How the CVE Works
CVE-2025-21557 is a Cross-Site Request Forgery (CSRF) vulnerability in Oracle Application Express (APEX) versions 23.2 and 24.1. The flaw allows a low-privileged attacker with network access via HTTP to exploit the application by tricking an authenticated user into executing unintended actions. The attack requires human interaction (e.g., clicking a malicious link) but can lead to unauthorized data modification (insert, update, delete) and partial data disclosure. The vulnerability stems from insufficient anti-CSRF protections in the affected component, enabling attackers to perform state-changing requests on behalf of the victim.
