The Events Calendar < 6.16.5.1 - Unauthenticated Event Aggregator Import Status Manipulation

Published Jul 27, 2026 · Updated Jul 27, 2026 · Assigned by WPScan

Description

The Events Calendar WordPress plugin before 6.16.5.1 does not perform an authorization check on one of its Event Aggregator import REST API routes and skips an integrity check for a particular status value, allowing unauthenticated attackers to mark existing import records as failed and to store arbitrary content in a hidden comment record.
