Security disclosure

One SQL injection finding reported through the operator's official channel.

SQL injection in a checkout flow

Responsible disclosure · Finnish fitness platform

I found an unauthenticated SQL injection in the promo-code validation of a public membership checkout. Testing showed it could be used to bypass payment. I reported the issue through the operator's official channel and coordinated the disclosure with them.
