Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the Oracle Application Express Quick Poll component of Oracle Database Server. The supported version that is affected is Prior to 20.2. Easily exploitable vulnerability allows low privileged attacker having Valid User Account privilege with network access via HTTP to compromise Oracle Application Express Quick Poll. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Application Express Quick Poll, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Application Express Quick Poll accessible data as well as unauthorized read access to a subset of Oracle Application Express Quick Poll accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Oracle Application Express installation and version
    Query the APEX version using SELECT version_no FROM apex_version; or access the About page in APEX Administration Services. Alternatively, check theords/\apex\..\utilities\about.htm page.
    Affected if The installed version is earlier than 20.2 (versions 5.x, 18.x, 19.x are all affected)
  2. Confirm Quick Poll component is accessible
    Navigate to the Quick Poll application or module within your APEX instance. Check if the component exists by accessing the Quick Poll application URL or reviewing the application builder for Quick Poll-enabled applications.
    Affected if Quick Poll module is present and accessible to authenticated users in the APEX installation
  3. Verify authenticated user access exists
    Review the APEX user accounts and application authentication schemes. Check if low-privileged users (non-admin) have accounts that can log in to applications containing Quick Poll functionality.
    Affected if There are authenticated users with access to any application that includes Quick Poll functionality
  4. Check for unauthorized data access indicators
    Review APEX activity logs and audit trails for the Quick Poll component. Query APEX workspace activity logs (APEX_WORKSPACE_ACTIVITY_LOG) for unusual read, insert, update, or delete operations on Quick Poll data from lower-privileged accounts.
    Affected if Low-privileged users have performed or can perform data operations on Quick Poll that should be restricted to higher-privileged roles

You are affected if Oracle Application Express version is earlier than 20.2 AND the Quick Poll component is in use with authenticated user access.
