What is CVE-2026-32944?
Parse Server is an open-source backend framework that enables developers to build applications on various infrastructures supporting Node.js. A vulnerability in versions before 9.6.0-alpha.21 and 8.6.45 allows an unauthenticated attacker to exploit deeply nested query condition operators, leading to a crash of the Parse Server process. This denial of service interrupts all connected clients. To address this issue, users are advised to upgrade to the latest versions and configure the requestComplexity.queryDepth server option to implement a depth limit, which is essential for maintaining application availability.
