The vulnerability was publicly disclosed on September 2, 2021, and affects users with Contributor-level permissions or higher. The issue stems from improper handling of the 'ids' attribute in the gallery shortcode (WPScan).

The exploitation of this vulnerability can result in unauthorized access to sensitive database information, including user password hashes. Additionally, the vulnerability allows for the manipulation of returned values and the deserialization of arbitrary objects, potentially leading to further security compromises (WPScan).
