Denial Of Service (DoS)

github.com/expr-lang/expr is vulnerable to denial of service DoS. The vulnerability is due to missing recursion depth limits in certain builtin functions, which allows an attacker to supply deeply nested or cyclic data structures and trigger infinite recursion leading to stack overflow and...

Parse Server 安全漏洞

Parse Server is an open-source backend developed by the Parse Platform. It can be deployed on any infrastructure that runs Node.js. There were security vulnerabilities in versions of Parse Server prior to 8.6.55 and 9.6.0-alpha.44. These vulnerabilities stemmed from the possibility for attackers ...

Uncontrolled Recursion

Overview parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js. Affected versions of this package are vulnerable to Uncontrolled Recursion via the pre-validation transform pipeline. An attacker can cause the server process to become...

GHSA-9FJP-Q3C4-6W3J Parse Server has a query condition depth bypass via pre-validation transform pipeline

Impact An attacker can send an unauthenticated HTTP request with a deeply nested query containing logical operators to permanently hang the Parse Server process. The server becomes completely unresponsive and must be manually restarted. This is a bypass of the fix for CVE-2026-32944. Patches The...
