CVE-2026-18050: Events Manager < 7.4 - Unauthenticated Pending Upload Disclosure via events-manager/v1/uploads
The Events Manager WordPress plugin before 7.4 does not perform any authorization check on a REST route that serves temporarily stored file uploads, allowing unauthenticated users to retrieve another user's in-progress upload when its temporary identifier is known. The identifier is high-entropy, is disclosed only to the uploader, and the file is removed on submission or by a scheduled cleanup, so a cross-user read is not achievable by guessing alone.
