CVE-2026-114395 polonel CVE debrief

Who should care

Defenders responsible for Trudesk deployments, particularly those using version 1.2.11 or earlier, should assess their exposure and take steps to verify and secure their environments. This includes reviewing access controls, monitoring for suspicious activity, and applying patches as available.

Why it matters

CVE-2026-114395 is an authorization bypass vulnerability in Trudesk that allows authenticated users to post messages as other users. Defenders should prioritize verifying access controls, monitoring for suspicious activity, and applying patches to prevent exploitation.

• Potential for authenticated users to post messages as other users, leading to misinformation or confusion.
• Possible impact on the integrity of conversations and messages within Trudesk.
• Need for defenders to verify and secure Trudesk deployments to prevent unauthorized message posting.
• Requirement for patching or updating Trudesk to prevent exploitation.

Technical summary

The vulnerability is caused by an incomplete fix for CVE-2022-1931 in Trudesk through version 1.2.11. This allows authenticated users to bypass authorization and post messages as other users by manipulating the owner and cId values in the POST /api/v1/messages/send request. The issue arises from the incomplete remediation of the original CVE-2022-1931 vulnerability, which did not fully address the authorization bypass. As a result, attackers can inject spoofed messages into conversations they do not belong to, potentially leading to misinformation or confusion. Defenders should prioritize verifying the authenticity of messages and ensuring proper authorization for message posting in Trudesk deployments. This A
