Vulnerability from github – Published: 2026-05-21 03:30 – Updated: 2026-05-21 03:30

Details

The Broadstreet plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.52.2 via the get_sponsored_meta AJAX action due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to disclose any private post metadata.

Severity ?

4.3 (Medium)
