CVE-2026-57821 in Apache Fineract
A SQL Injection vulnerability exists in Apache Fineract's Office Search API (GET /api/v1/offices) in versions up to and including 1.14.0. The orderBy request parameter is concatenated into a SQL query without sufficient validation, allowing an authenticated user with permission to view offices to inject arbitrary SQL via a crafted orderBy value. This is a bypass of the ColumnValidator fix introduced for CVE-2024-32838, which does not detect bare subqueries in the ORDER BY position. This can be leveraged to perform time-based blind SQL injection for data exfiltration. Because the injected query blocks the database connection for its full duration, concurrent exploitation can exhaust the application's database connection pool, resulting in denial of service for other users. Users are recommended to upgrade to a version containing the fix.

CVE-2026-53902 MyComplianceOffice Group Membership Privilege Escalation
MCO does not properly enforce authorization checks in the /customer/servlet/mco/webapi/profile-sections/group-membership endpoint. An authenticated user can modify their group membership without proper authorization checks, allowing privilege escalation. An attacker can add themselves to arbitrary groups by supplying a valid group ID, which can be obtained via other application functionalities (e.g. /customer/servlet/mco/webapi/group/picker/groups), provided he has necessary permissions, or potentially inferred through brute-force techniques. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
Updated Jul 15, 2026
CVE-2026-53903 MyComplianceOffice IDOR Document Disclosure Vulnerability
MCO is vulnerable to an Insecure Direct Object Reference (IDOR) vulnerability in the /customer/servlet/mco/webapi/trading-document/fetchPdfStatement endpoint. The application does not properly validate whether an authenticated user is authorized to access a requested document, allowing direct retrieval based on a user-supplied identifier. An attacker can access trading documents belonging to other users by providing a valid document ID. Although exploitation requires guessing the identifier, predictable ID patterns enable feasible enumeration, leading to unauthorized disclosure of sensitive information. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
Updated Jul 15, 2026
CVE-2026-53904 MCO Password Reset Denial of Service Vulnerability
MCO is vulnerable to Account Denial of Service due to improper implementation of password reset functionality. Each password reset request invalidates previously set password as well as previously issued temporary passwords, furthermore, password resets are not limited in any way. An attacker who provides victim's email and answer to their security question, can successfully initiate the reset process and continuously invalidate credentials, effectively locking the victim out of their account. Answering security questions has a limited number of tries which lowers the risk of this vulnerability. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
Updated Jul 15, 2026
CVE-2026-53905 MyComplianceOffice Authorization Bypass Vulnerability
MCO does not properly enforce authorization checks in the /customer/servlet/mco/webapi/admin-view-hierarchy/get-acl-tree-structure endpoint. An authenticated, low-privileged user can retrieve administrator access control structures without proper authorization checks. This may expose sensitive permission mappings and internal configuration details. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
Updated Jul 15, 2026
CVE-2026-53906 MyComplianceOffice Path Traversal Information Disclosure Vulnerability
MCO is vulnerable to Path Disclosure and Path Traversal in file handling functionality related to data export and upload. Improper validation of the filename parameter allows writing files to arbitrary locations as well as indirect disclosure of absolute server paths through error messages. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
Updated Jul 15, 2026
CVE-2026-53907 MyComplianceOffice Stored XSS Vulnerability
MCO is vulnerable to Stored Cross‑Site Scripting (XSS) via the application logo upload functionality. An attacker with the ability to change the application logo can upload a crafted SVG file containing malicious JavaScript code that is executed when the logo is rendered or opened. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
Updated Jul 15, 2026
CVE-2026-53908 MyComplianceOffice User Enumeration Vulnerability
MCO is vulnerable to User Enumeration through authentication-related functionalities. The application returns distinguishable responses for valid and invalid users during username reminder and password reset operations. An attacker can leverage these differences to enumerate valid usernames and email addresses. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
Updated Jul 15, 2026
CVE-2026-53909 MyComplianceOffice File Upload Validation Vulnerability
MCO does not correctly validate types of uploaded files. File upload validation functionality relies only on client-side checks, which can be bypassed. An authorized, low-privileged attacker can upload files with arbitrary types to the server. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
