CVE-2026-33624 Parseplatform — Exploit & Vulnerability Details LOW

Parameter	Value
CVSS	2.1 (LOW)
Affected Versions	9.0.0 — 9.6.0
Fixed In	8.6.60
Type	CWE-367 (Time-of-check Time-of-use (TOCTOU))
Vendor	Parseplatform
Public PoC	No

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.60 and 9.6.0-alpha.54, an 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. This issue has been patched in versions 8.6.60 and 9.6.0-alpha.54.
