Unauthenticated settings modification via unchecked REST action
Published Jun 3, 2023 · Updated Apr 8, 2026
Missing authorization in Online Booking & Scheduling Calendar for WordPress by vcita 4.4.2 and earlier allows remote attackers to modify settings. The unauthenticated /wp-json/vcita-wordpress/v1/actions/auth route invokes processAction without a capability check and stores attacker-supplied account connection parameters in the database. No account or user interaction is required; a crafted POST can replace the connected business identity and other plugin configuration.
