Description
The Super Progressive Web Apps WordPress plugin up to version 2.2.43 contains a stored cross-site scripting (XSS) vulnerability. This flaw arises from improper sanitization and escaping of the offline message setting, allowing administrator-level users to inject malicious scripts. These scripts execute in users' browsers when the offline snackbar is triggered. The vulnerability has a medium severity rating and no known exploits in the wild. No official patch or remediation guidance has been provided yet.
