gorest InMemorySecret2FA race condition allows process crash via concurrent map access (CWE-362)
The InMemorySecret2FA in database/model/twoFA.go was defined as a package-level map[uint64]Secret2FA — a bare Go map with no synchronization primitive. Multiple HTTP handlers in handler/login.go and handler/twoFA.go read from and wrote to this map concurrently. Go's runtime detects unsynchronized concurrent map access and throws an unrecoverable fatal error, which crashes the entire process. This is a CWE-362 race condition: the shared resource (the map) is accessed concurrently without proper synchronization, and …
