Technical Analysis

CVE-2026-34836 is a missing authorization vulnerability (CWE-862) in the Combodo iTop IT service management tool. Versions before 3.2.3 improperly enforce access control in ajax.render.php and ajax.document.php, enabling document access without verifying user permissions. This could lead to unauthorized disclosure of sensitive information. The vulnerability has been addressed in version 3.2.3.

Potential Impact

An attacker with low privileges can access documents they are not authorized to view, resulting in a confidentiality breach. There is no impact on integrity or availability reported.

Mitigation Recommendations

Upgrade to Combodo iTop version 3.2.3 or later, where this authorization issue has been fixed.
