What it is

🚨 A simple password reset request is all it takes to hijack an account in affected versions of OctoberCMS! ⚡ Think of it as a restaurant that allows anyone to change a reservation just by asking nicely, completely ignoring the need for proper verification. This flaw lets attackers gain access to accounts as easily as changing a dinner reservation without checking ID. An attacker could potentially lock users out of their accounts, access sensitive information, make unauthorized changes, or even cause embarrassment for businesses relying on this CMS. It's a serious breach that could lead to data loss and reputational damage if left unaddressed!
