+  "summary": "Parse Server: MFA recovery code single-use bypass via concurrent requests",
+  "details": "### Impact\n\nAn attacker who obtains a user's password and a single MFA recovery code can reuse that recovery code an unlimited number of times by sending concurrent login requests. This defeats the single-use design of recovery codes. The attack requires the user's password, a valid recovery code, and the ability to send concurrent requests within milliseconds.\n\n### Patches\n\nThe login handler now uses optimistic locking when updating auth data that contains consumed single-use tokens. If a concurrent request has already modified the recovery array, the update fails and the login is rejected.\n\n### Workarounds\n\nThere are no known workarounds.",
