CVE-2026-31840 describes a critical SQL Injection vulnerability affecting Parse Server, a backend service for mobile apps. An attacker can exploit this flaw to inject malicious SQL code into the PostgreSQL database through improper escaping of sub-field values in dot-notation queries. This vulnerability impacts versions prior to 9.6.0-alpha.2 and requires immediate attention to prevent potential data breaches.
The SQL Injection vulnerability in Parse Server allows an attacker to manipulate database queries by injecting arbitrary SQL code. By crafting malicious sort requests using dot-notation field names, an attacker can bypass security measures and directly interact with the underlying PostgreSQL database. This could lead to unauthorized access, modification, or deletion of sensitive data stored within the Parse Server database, including user credentials, application data, and configuration information. The potential blast radius is significant, as a successful exploit could compromise the entire application and its associated data. While the description explicitly mentions sort, the potential for exploitation via distinct and where parameters expands the attack surface.
CVE-2026-31840 was publicly disclosed on March 10, 2026. The vulnerability's severity is rated as CRITICAL (CVSS 9.5). As of the current date, there are no publicly available proof-of-concept exploits. The vulnerability is not currently listed on the CISA KEV catalog. Given the ease of SQL injection exploitation and the potential impact, it is likely that attackers will actively seek to exploit this vulnerability once a proof-of-concept is released.
Organizations and developers utilizing Parse Server with PostgreSQL databases are at risk. This includes applications relying on Parse Server for backend functionality, particularly those handling sensitive user data or financial transactions. Those using older, unpatched versions of Parse Server are especially vulnerable.

The primary mitigation for CVE-2026-31840 is to upgrade Parse Server to version 9.6.0-alpha.2 or later, which includes a fix that properly escapes characters in dot-notation sub-field values. Since no workaround is explicitly provided, upgrading is the only recommended solution. If upgrading is not immediately feasible, consider implementing strict input validation on all dot-notation field names used in queries to prevent the injection of malicious SQL code. This could involve whitelisting allowed characters or using parameterized queries to ensure that user-supplied input is treated as data rather than executable code. Regular security audits and penetration testing can also help identify and address potential vulnerabilities.
Aktualisieren Sie Parse Server auf Version 9.6.0-alpha.2 oder höher oder auf Version 8.6.28 oder höher. Dies behebt die SQL-Injection-Schwachstelle in der PostgreSQL-Datenbank, indem Subfeldwerte in Punktnotation-Abfragen korrekt escaped werden.
