Project: Embed [1] Date: 2022-May-25 Security risk: *Moderately critical* 13∕25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2] Vulnerability: Cross Site Scripting

Description:  The Drupal Embed module provides a filter to allow embedding various embeddable items like entities in content fields.

In certain circumstances, the filter could allow an unprivileged user to inject HTML into a page when it is accessed by a trusted user with permission to embed items. In some cases, this could lead to cross-site scripting (XSS).

Solution:  Install the latest version:

* If you use the Embed module for Drupal 8.x or 9.x, upgrade to Embed 8.x-1.5 [3]
