CVE-2026-21922 is a vulnerability in Oracle Planning and Budgeting Cloud Service version 25.04.07, specifically within the EPM Agent component. The flaw allows a high privileged attacker who already has logon access to the underlying infrastructure hosting the service to compromise the Oracle Planning and Budgeting Cloud Service. Exploitation requires human interaction from a user other than the attacker, indicating some form of social engineering or user-triggered action is necessary. The vulnerability does not expose confidentiality or availability but allows unauthorized modification, creation, or deletion of critical data managed by the service, thus impacting data integrity. The attack vector is local (AV:L), with low attack complexity (AC:L), requiring high privileges (PR:H) and user interaction (UI:R). The scope remains unchanged (S:U), and the impact is limited to integrity (I:H) without affecting confidentiality (C:N) or availability (A:N). Oracle recommends updating the EPM Agent component to remediate the issue. No public exploits have been reported to date, but the vulnerability poses a risk to organizations relying on Oracle’s cloud-based enterprise performance management solutions, especially where attackers may gain privileged infrastructure access and leverage social engineering to trigger the exploit.

For European organizations, this vulnerability poses a significant risk to the integrity of critical financial and operational data managed within Oracle Planning and Budgeting Cloud Service. Unauthorized data modification or deletion could disrupt budgeting, forecasting, and financial planning processes, potentially leading to erroneous business decisions, regulatory compliance issues, and financial losses. Given that the attack requires high privileged access and user interaction, the threat is more relevant in environments where insider threats or compromised privileged accounts exist. Organizations in finance, manufacturing, and public sectors using Oracle’s cloud services are particularly vulnerable. The impact is compounded by the critical nature of the data handled by the service, which often supports strategic decision-making and regulatory reporting. While confidentiality and availability are not directly impacted, the integrity compromise alone can have cascading effects on business operations and trustworthiness of financial data.

European organizations should immediately verify the version of Oracle Planning and Budgeting Cloud Service and ensure the EPM Agent is updated to the latest patched version as recommended by Oracle. Access to the underlying infrastructure must be tightly controlled, with strict privilege management and monitoring to prevent unauthorized high privileged logons. Implement robust user awareness training to reduce the risk of successful social engineering attacks that could trigger the required human interaction. Employ multi-factor authentication and session monitoring for privileged accounts to detect and prevent misuse. Regularly audit logs and configurations of the Oracle cloud environment to identify suspicious activities. Additionally, segment the infrastructure hosting Oracle services to limit lateral movement and isolate critical components. Establish incident response plans specific to cloud service compromises involving data integrity issues. Finally, coordinate with Oracle support for any additional security advisories or mitigations.
