CVE-2026-114391 easysoft CVE debrief

Who should care

Defenders responsible for ZenTao PMS installations should assess exposure and prioritize upgrading to version 22.3 or later. They should also review access controls and monitor for suspicious activity related to the vulnerable methods.

Why it matters

CVE-2026-114391 is an authorization bypass vulnerability in ZenTao PMS before version 22.3. It allows logged-in users to bypass group-based ACL checks for methods containing 'ajax', potentially enabling minimal-privilege users to perform sensitive actions. Defenders should prioritize verifying exposure and upgrading to version 22.3 or later.

• Potential data exposure through unauthorized access to sensitive information.
• Possible escalation of privileges for minimal-privilege users.
• Risk of unauthorized changes to tables or data.
• Need for verification of current version and exposure of ZenTao PMS installations.

Technical summary

The vulnerability exists in the commonModel::isOpenMethod() function of ZenTao PMS before version 22.3. It allows logged-in users to bypass group-based ACL checks for methods containing 'ajax', potentially enabling minimal-privilege users to read data, obtain database credentials, trigger CI jobs, and alter tables. This could lead to unauthorized access to sensitive information, escalation of privileges, and potential data breaches. Defenders should prioritize verifying exposure of ZenTao PMS installations and upgrading to version 22.3 or later. They should also review and restrict access to sensitive data and systems that could be accessed through the vulnerable methods, and monitor for suspicious activity.

Defensive priority

Defenders should prioritize verifying exposure of ZenTao PMS installations and upgrading to version 22.3 or later. They should also review and restrict access to sensitive data and systems that could be accessed through the vulnerable methods.
