Very, on the 2019 and especially just after Facebook’s Cambridge Analytica drama, Tinder performed some damn a great occupations protecting by themselves from the regular, OWASP Top 10 vulnerabilities

Just after understanding IncludeSecurity’s blog post I happened to be shocked from the exactly how effortless you to definitely are. No IDOR is actually needed, zero complex CSRF otherwise a keen XSS. All the details is there, at no cost, for everyone to take and you can punishment.
