CVE-2026-21924: Vulnerability in the Oracle Utilities Application Framework product of Oracle Utilities Applications (compo...

Vulnerability in the Oracle Utilities Application Framework product of Oracle Utilities Applications (component: General). Supported versions that are affected are 4.4.0.3.0, 4.5.0.0.0, 4.5.0.1.1, 4.5.0.1.3, 4.5.0.2.0, 25.4 and 25.10. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Utilities Application Framework. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Utilities Application Framework, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Utilities Application Framework accessible data as well as unauthorized read access to a subset of Oracle Utilities Application Framework 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).

Security readout for executives and security teams

Plain-English summary

CVE-2026-21924 affects Oracle Utilities Application Framework. A low-privileged user with HTTP network access could, with another user’s interaction, read some accessible data and modify some data. The issue is medium severity, but it matters for utilities environments because integrity changes in business application data can create operational and compliance impact.

Executive priority

Treat as a timely patch-management item, not an emergency based on current evidence. Prioritize organizations running affected versions in production, especially where many users can access the application over HTTP or where data integrity is business-critical.

Technical view

Oracle reports an easily exploitable vulnerability in Oracle Utilities Application Framework, component General. Affected supported versions are 4.4.0.3.0, 4.5.0.0.0, 4.5.0.1.1, 4.5.0.1.3, 4.5.0.2.0, 25.4, and 25.10. CVSS 3.1 is 5.4: AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N.

Likely exposure

Exposure is most likely where affected Oracle Utilities Application Framework instances are reachable over HTTP by authenticated low-privileged users. Systems with broad internal access, shared user populations, or internet-adjacent portals deserve faster review.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires low privileges, network access via HTTP, and human interaction by someone other than the attacker. Oracle notes scope change, meaning other products may be significantly impacted.

Researcher notes

No CWE is provided in the source bundle. The advisory states confidentiality and integrity impacts only, with no availability impact. Avoid assuming exploitability beyond Oracle’s CVSS details: low privilege, network vector, required user interaction, and changed scope.

Mitigation direction

  • Identify Oracle Utilities Application Framework deployments and versions.
  • Prioritize affected versions listed by Oracle for review.
  • Follow Oracle January 2026 CPU advisory remediation guidance.
  • Restrict HTTP access to trusted users and networks where feasible.
  • Review low-privileged accounts and remove unnecessary access.
  • Monitor for unusual reads, updates, inserts, or deletes in accessible data.

Validation and detection

  • Confirm deployed Oracle Utilities Application Framework version.
  • Check whether the instance matches Oracle’s affected version list.
  • Verify remediation status against Oracle’s January 2026 CPU advisory.
  • Review application logs for suspicious data modification activity.
  • Validate access controls for low-privileged HTTP users.
  • Document any dependent Oracle Utilities products in scope.
