This includes updating to version 8.19 or later, and monitoring for potential exploitation attempts. Additionally, operators, platform administrators, and security teams should review the vulnerability and take necessary actions to protect their systems.

Technical summary

The CVE-2026-25567 vulnerability is caused by the insecure direct object reference (IDOR) in the card comment creation API of Wekan. The API accepts an authorId from the request body, which allows an authenticated user to spoof the recorded comment author by supplying another user's identifier. This could potentially be used to manipulate the recorded authors of comments, which could have implications for the integrity of the information stored in Wekan. The vulnerability has a CVSS score of 5.3 and a severity of MEDIUM.
