Technical Analysis
The Eventin WordPress plugin versions prior to 4.1.19 do not properly restrict authorization for guest checkout tokens on orders. This missing authorization (CWE-862) allows unauthenticated users to manipulate their unpaid orders and mark them as completed, resulting in issuance of valid paid tickets without payment.
Potential Impact
An attacker can exploit this vulnerability to bypass payment requirements and obtain valid tickets without paying. This impacts the integrity of order processing and revenue protection but does not affect confidentiality or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, monitor vendor channels for updates and avoid using vulnerable versions if possible.
