## What is CVE-2026-91077?

CVE-2026-91077 is a low-severity missing authorization vulnerability in Unknown Event Booking Manager for WooCommerce, published on 23 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

The Event Booking Manager for WooCommerce  WordPress plugin before 5.7.3 does not restrict its event listing query to events the requesting user is permitted to read, so users with contributor-level access and above can retrieve other authors' private, draft and trashed events, together with event detail the standard listing does not show them. This discloses private events and their content that WordPress withholds from users lacking the read_private_posts capability.
