WordPress GetPaid Plugin 2.4.6 contains an HTML injection vulnerability that allows authenticated attackers to inject arbitrary HTML code by exploiting the Help Text field in payment forms.

Technical Analysis
CVE-2021-47948 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
