AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions The Post Grid WordPress plugin versions prior to 7.5.0

Description The issue allows high privilege users, such as Editor and above, to perform Stored Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed, for example in multisite setups. This is due to the plugin not sanitizing and escaping some of its Grid settings.

Recommendations For versions prior to 7.5.0, update to version 7.5.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the Grid settings to minimize the risk of exploitation.
