Generally, Tinder paid a susceptability for free.
Really, on the 2019 and particularly just after Facebook’s Cambridge Analytica crisis, Tinder did certain damn a employment securing by themselves about typical, OWASP Top weaknesses
Shortly after discovering IncludeSecurity’s article I was amazed of the just how effortless you to are. No IDOR is requisite, zero complex CSRF otherwise an enthusiastic XSS. What is there, free-of-charge, for everyone for taking and you can abuse.
