Defenders responsible for WordPress installations with the Online Payments with iK Pay Gateway plugin should assess exposure and prioritize verification and remediation. This includes reviewing the plugin version, verifying the authenticity of payment gateway callbacks, and ensuring compensating controls are in place for exposed systems. Security teams and vulnerability management teams should also be aware of the potential impact and plan accordingly.

Why it matters
