CVE-2026-33323 Parseplatform — Exploit & Vulnerability Details MEDIUM

Parameter	Value
CVSS	6.3 (MEDIUM)
Affected Versions	9.0.0 — 9.6.0
Fixed In	8.6.51
Type	CWE-204
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 8.6.51 and 9.6.0-alpha.40, the Pages route and legacy PublicAPI route for resending email verification links return distinguishable responses depending on whether the provided username exists and has an unverified email. This allows an unauthenticated attacker to enumerate valid usernames by observing different redirect targets.

The existing emailVerifySuccessOnInvalidEmail configuration option, which is enabled by default and protects the API route against this, did not apply to these routes. This issue has been patched in versions 8.6.51 and 9.6.0-alpha.40.
