CVE-2026-22230 is an authorization bypass vulnerability classified under CWE-863 in the OPEXUS eCASE Audit product, specifically affecting version 11.4.0. The flaw arises because the application relies on client-side controls to enforce administrative restrictions on certain functions or UI elements such as buttons. An authenticated attacker can manipulate client-side JavaScript or craft custom HTTP requests to invoke these disabled or blocked functions, effectively bypassing the intended authorization mechanisms. This vulnerability allows attackers to perform unauthorized actions that should have been restricted by administrators, potentially exposing sensitive data or altering system behavior. The vulnerability has a CVSS 3.1 base score of 7.6, indicating high severity, with the vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L, meaning it can be exploited remotely over the network with low attack complexity, requires low privileges (authenticated user), no user interaction, and impacts confidentiality highly, with limited integrity and availability impacts. The issue was addressed and fixed in eCASE Platform version 11.14.1.0. No public exploits or active exploitation have been reported so far. The root cause is improper authorization checks on the server side, relying excessively on client-side enforcement, which is inherently insecure. This vulnerability highlights the critical need for robust server-side authorization validation in web applications handling sensitive audit data.

For European organizations, the impact of this vulnerability can be significant, especially for those in sectors such as finance, healthcare, government, and critical infrastructure that rely on OPEXUS eCASE Audit for compliance and audit management. Unauthorized access to restricted functions could lead to exposure of confidential audit data, manipulation of audit records, or unauthorized changes to system configurations, undermining data integrity and trustworthiness. This could result in regulatory non-compliance, reputational damage, and potential financial penalties under GDPR and other data protection laws. The vulnerability's ability to bypass administrative controls also increases insider threat risks, as low-privileged authenticated users could escalate their capabilities. Although availability impact is limited, the confidentiality breach alone is critical given the sensitive nature of audit data. The lack of known exploits reduces immediate risk but does not eliminate the threat, making proactive patching and mitigation essential.

European organizations should immediately upgrade affected OPEXUS eCASE Audit instances to version 11.14.1.0 or later, where the vulnerability is fixed. Until patching is complete, implement strict network segmentation and access controls to limit authenticated user privileges to the minimum necessary. Employ web application firewalls (WAFs) with custom rules to detect and block anomalous HTTP requests that attempt to access disabled functions. Conduct thorough audits of user roles and permissions to ensure no excessive privileges are granted. Enable detailed logging and monitoring of user actions within the eCASE Audit platform to detect potential exploitation attempts. Educate administrators and users about the risks of client-side manipulation and enforce secure development practices for any custom integrations. Finally, consider deploying runtime application self-protection (RASP) tools to detect and prevent unauthorized function invocations in real time.
