AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in WeKan versions up to 8.20, specifically in the setBoardOrgs function of the models/boards.js file within the REST API component. It involves improper authorization caused by manipulation of certain arguments such as item.cardId, item.checklistId, or card.boardId. This flaw allows an attacker to potentially perform unauthorized actions remotely, although the attack complexity is high and exploitability is difficult. Upgrading to version 8.21 addresses this issue.
How can this vulnerability impact me? :
The vulnerability can lead to improper authorization, meaning an attacker might gain access to or manipulate board-related data they should not have permission to. This could result in unauthorized changes or exposure of sensitive information within the WeKan application. However, the attack requires high complexity and is difficult to exploit.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
