### Summary An attacker can exploit a chain of vulnerabilities, including a Denial of Service (DoS) flaw and in-memory data storage weakness, to effectively bypass the application's brute force login protection. This makes the application susceptible to brute force attacks, compromising the security of all user accounts. ### Details The issue arises from two main vulnerabilities: 1. The application crashes due to a previously described DoS vulnerability caused by unsafe array modifications in a multi-threaded environment. 2. The application saves the data of failed login attempts in-memory, without persistent storage. When the application crashes and restarts, this data is lost, resetting the brute force protections. ```go // LoginAttempts is a timestamped counter for failed login attempts type LoginAttempts struct { // Time of the last failed login LastFailed time.Time `json:"lastFailed"` // Number of consecutive login failures FailCount int `json:"failCount"` } ``` By chainin...
