CVE-2023-2407

The Event Registration Calendar By vcita plugin, versions up to and including 3.10.0, and Online Payments – Get Paid with PayPal, Square & Stripe plugin, for WordPress are vulnerable to Cross-Site Request Forgery. This is due to missing nonce validation in the ls_parse_vcita_callback() function. This makes it possible for unauthenticated attackers to modify the plugin's settings and inject malicious JavaScript via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
