Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
