Twitter Fixes Serious Flaw That Allowed Unauthorised Deletion of User Credit Card Info

Earlier this month Twitter launched a HackerOne initiative that rewarded security experts for correctly identifying serious bugs on the platform. The program pays out a minimum of $140 for any qualifying vulnerability, with no maximum reward – indeed, the bounty is scaled against the severity of the flaw.

This week Twitter has patched a hole that would have allowed a hacker to openly delete any number of account credit cards used for ad payments on Twitter, potentially costing the company millions in revenue.
