CVE-2026-32944 Parse Server crash via deeply nested query condition operators

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.21 and 8.6.45, an unauthenticated attacker can crash the Parse Server process by sending a single request with deeply nested query condition operators. This terminates the...

Uncontrolled Recursion

Overview nltk is a Natural Language Toolkit NLTK is a Python package for natural language processing. Affected versions of this package are vulnerable to Uncontrolled Recursion via the JSONTaggedDecoder.decodeobj function in jsontags.py. An attacker can cause the application to crash by submittin...

Natural Language Toolkit (NLTK) has unbounded recursion in JSONTaggedDecoder.decode_obj() may cause DoS

Summary JSONTaggedDecoder.decodeobj in nltk/jsontags.py calls itself recursively without any depth limit. A deeply nested JSON structure exceeding sys.getrecursionlimit default: 1000 will raise an unhandled RecursionError, crashing the Python process. Affected code File: nltk/jsontags.py, lines...
