CVE-2025-47539Known exploitationPublic exploitNetwork attack vector

Unauthenticated administrator creation via speaker import

Published May 23, 2025 · Updated Apr 28, 2026

Incorrect privilege assignment in Arraytics Eventin 4.0.26 and earlier allows remote attackers to create administrator accounts via speaker import. The /wp-json/eventin/v2/speakers/import route accepts unauthenticated uploads because import_item_permissions_check returns true, and SpeakerImporter passes an attacker-supplied role into user creation. Network access to an active Eventin site is sufficient; an imported administrator can reset the account password and take full control of the WordPress site.
