Technical Analysis
The Eventin WordPress plugin versions prior to 4.1.22 contain a missing authorization vulnerability (CWE-862) in one of its REST API namespaces. This flaw permits unauthenticated attackers to retrieve non-published content, including drafts, pending posts, private posts belonging to other users, and password-protected post contents without proper access controls. The vulnerability does not require user interaction or privileges and impacts confidentiality but not integrity or availability.
Potential Impact
An attacker can access sensitive unpublished content and password-protected post contents without authentication. This leads to information disclosure of potentially sensitive data belonging to other users. There is no impact on data integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch link is provided at this time. Until a patch is available, restrict access to the affected REST API namespace or disable the plugin if possible to prevent unauthorized data exposure.
