What is CVE-2026-15208?
CVE-2026-15208 is a medium-severity vulnerability in Unknown RegistrationMagic, published on 6 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The RegistrationMagic WordPress plugin before 6.0.9.5 does not compare the verified PayPal capture's amount, currency, payee, or prior use against the registration it is finalising: its server-side check only confirms the capture status is COMPLETED. An unauthenticated attacker can therefore finalise an expensive paid registration with any genuinely-completed low-value capture, and replay a single capture across unlimited registrations because captures are not de-duplicated.
Weakness: CWE-345
