WordPress · Popup Maker · CVE-2022-1104
**Name of the Vulnerable Software and Affected Versions**
Popup Maker WordPress plugin versions prior to 1.16.5
**Description**
The issue concerns the Popup Maker WordPress plugin, which does not properly sanitize and escape some of its popup settings. This could allow high-privilege users, such as administrators, to perform Stored Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed.
**Recommendations**
For versions prior to 1.16.5, update to version 1.16.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the plugin's settings to minimize the risk of exploitation. Avoid using the vulnerable popup settings until the issue is resolved.
