SB2026063048 - Incorrect authorization in Parse Server

Description

This security bulletin contains information about 1 vulnerability.

1) Incorrect authorization (CVE-ID: CVE-2026-50008)

CWE-ID: CWE-863 - Incorrect Authorization

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to bypass route-based access restrictions.

The vulnerability exists due to improper access control in the /batch handler when processing batch sub-requests. A remote attacker can send a specially crafted batch request to bypass route-based access restrictions.

Only deployments that enable routeAllowList and allow access to the batch route are affected. Inner-route authentication, ACL, and CLP checks still apply.

Remediation

Install update from vendor's website.
