Event Tickets And Registration
Monthly
Unauthenticated payment credential hijacking in the Event Tickets and Registration WordPress plugin (StellarWP, all versions ≤5.27.4) allows any remote attacker to silently replace the site's Stripe merchant account credentials - access tokens, publishable keys, and account ID - via a missing capability check on the plugin's Stripe OAuth return endpoint. Once the attacker's own Stripe credentials are stored, all subsequent ticket purchases by legitimate customers are processed into the attacker's account with no visible indication to the buyer or site administrator. No public exploit has been identified at time of analysis, but the fully unauthenticated AV:N/AC:L/PR:N attack surface makes opportunistic mass exploitation straightforward.
Broken object-level authorization in the Event Tickets and Registration WordPress plugin before 5.29.0.1 allows any contributor-level (or higher) WordPress user to overwrite the seating layout, ticket inventory, and attendee seat assignments for events they do not own. The flaw stems from insufficient ownership verification on seating-related actions, meaning a low-privileged authenticated user can manipulate another author's event data without restriction. No public exploitation in the wild has been confirmed by CISA KEV, but a public proof-of-concept exists per WPScan reporting, and the EPSS score of 0.13% (3rd percentile) reflects minimal observed scanning or exploitation activity at time of analysis.
Unauthenticated order status manipulation is possible in the Event Tickets and Registration WordPress plugin across all versions before 5.29.0.1, due to a completely absent authorization check on an order-management REST endpoint. Any remote actor - with no credentials or privileges - can alter the status of existing orders, enabling fraud scenarios such as marking unpaid orders as completed. A publicly available exploit exists per WPScan; however, EPSS at 0.14% (4th percentile) indicates mass exploitation has not materialized at time of analysis, and the vulnerability is not listed in CISA KEV.
Stored cross-site scripting in the Event Tickets and Registration WordPress plugin before 5.28.4 enables Editors and above to inject malicious scripts in event titles, which execute against higher-privileged users on multisite setups when they view the ticket history log. The vulnerability has a low CVSS of 3.5 and a low EPSS of 0.15%, but exploit code is publicly available. A patch in version 5.28.4 is available from the vendor.
