parse-server is vulnerable to Race Condition
21
Low Risk
This Affects:
parse-serverTL;DR
Concurrent /login requests can both validate the same SMS one-time password because optimistic locking only constrained array-shaped auth fields while SMS OTP values are stored as primitives, so two racing updates can succeed and issue separate sessions. The maintenance release generalizes optimistic locking to primitive and array auth fields via a shared helper so concurrent consumers lose the update predicate and see a controlled auth failure instead.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
