CVE-2026-114392 polonel CVE debrief

Who should care

Defenders responsible for Trudesk instances, particularly those with authenticated user access, should assess exposure and prioritize verification of ticket reading access controls.

Why it matters

CVE-2026-114392 is a medium-severity authorization bypass vulnerability in Trudesk that allows authenticated users to read tickets outside their groups. Defenders should prioritize verifying exposure, assessing potential for ticket enumeration attacks, and updating access controls to prevent unauthorized ticket reading.

• Authenticated users may be able to read sensitive ticket information outside their groups
• Enumeration of ticket UIDs could lead to unauthorized access to ticket data
• Defenders need to verify exposure and update access controls to prevent unauthorized ticket reading
• Remediation priority is high for Trudesk instances with high volumes of ticket activity

Technical summary

The Trudesk application through version 1.2.11 contains an authorization bypass vulnerability. This vulnerability allows authenticated users to read tickets outside their groups by making a GET request to /api/v1/tickets/:uid. An attacker can exploit this by enumerating sequential ticket UIDs to access the subject, issue, comments, owner, and assignee of every ticket. The CVE record and NVD entry provide details on the authorization bypass vulnerability in Trudesk. Defenders should prioritize verifying exposure of Trudesk instances to authenticated users and assessing the potential for ticket enumeration attacks.

Defensive priority

Defenders should prioritize verifying exposure of Trudesk instances to authenticated users and assessing the potential for ticket enumeration attacks.

Recommended defensive actions

• Verify Trudesk instance exposure to authenticated users
• Assess potential for ticket enumeration attacks
• Review and update access controls for ticket reading
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
