Official Description

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.13 and 8.6.26, the LDAP authentication adapter is vulnerable to LDAP injection. User-supplied input (authData.id) is interpolated directly into LDAP Distinguished Names (DN) and group search filters without escaping special characters. This allows an attacker with valid LDAP credentials to manipulate the bind DN structure and to bypass group membership checks. This enables privilege escalation from any authenticated LDAP user to a member of any restricted group. The vulnerability affects Parse Server deployments that use the LDAP authentication adapter with group-based access control. This vulnerability is fixed in 9.5.2-alpha.13 and 8.6.26.

Technical Analysis

CVE-2026-31828 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
