Input validation vulnerability in Accept Donations with PayPal & Stripe 1.4.4

A plugin called “Accept Donations with PayPal & Stripe” for the website platform WordPress has a security issue. This means that in versions 1.4.4 and earlier, the plugin does not properly protect against malicious code being inserted through a parameter called “rf.” This can allow attackers who are not logged in to add their own harmful scripts to pages, which will run if a user clicks on a specific link.
