Summary
The Eventin WordPress plugin before version 4.1.22 does not restrict access to non-published content by status or ownership in one of its REST API namespaces. This allows unauthenticated users to retrieve draft, pending and private posts belonging to other users, along with the passwords and contents of password-protected ones.
Risk Assessment
The risk includes disclosure of confidential content, including private and password-protected posts, which could compromise user privacy and data security. Attackers may also obtain post passwords, leading to further breaches.
Recommendation
Update the Eventin plugin to version 4.1.22 or later. Also review REST API access logs for unauthorized requests.
