CVE-2026-53909 (GCVE-0-2026-53909)
Vulnerability from nvd – Published: 2026-07-01 11:59 – Updated: 2026-07-01 13:37
VLAI
Title
Arbitrary File Upload in MCO
Summary
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.

Title
User Enumeration in MCO
Summary
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.

CVE-2026-53905 (GCVE-0-2026-53905)
Vulnerability from nvd – Published: 2026-07-01 11:58 – Updated: 2026-07-01 13:40

Title
Unauthorized Access to Administrator ACL View in MCO
Summary
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.

User Enumeration in MCO
Summary
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.

Stored Cross‑Site Scripting in MCO
Summary
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.

CVE-2026-53906 (GCVE-0-2026-53906)
Vulnerability from cvelistv5 – Published: 2026-07-01 11:58 – Updated: 2026-07-01 13:39

Title
Path Disclosure and Path Traversal in MCO
Summary
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.

CVE-2026-53905 (GCVE-0-2026-53905)
Vulnerability from cvelistv5 – Published: 2026-07-01 11:58 – Updated: 2026-07-01 13:40

Title
Unauthorized Access to Administrator ACL View in MCO
Summary
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.
