A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Groundhogg Inc. HollerBox WordPress plugin versions 2.3.2 and below. The vulnerability was identified on September 1, 2023, and affects users with administrator privileges (Patchstack).

Technical details

The vulnerability stems from the plugin's failure to properly validate and escape certain parameters, which could enable users with admin roles to perform Stored Cross-Site Scripting attacks, even in scenarios where the unfilteredhtml capability is disabled, such as in multisite setups.

Impact
