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...

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.3, the pyasn1 library is vulnerable to a Denial of Service DoS attack caused by uncontrolled recursion when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing thousands of nested SEQUENC...

GHSA-9XP9-J92R-P88V Parse Server crash via deeply nested query condition operators
Impact An unauthenticated attacker can crash the Parse Server process by sending a single request with deeply nested query condition operators. This terminates the server and denies service to all connected clients. Patches A depth limit for query condition operator nesting has been added via the...
Uncontrolled recursion DoS in JustHTML() via deeply nested HTML
Summary justhtml through 1.9.1 allows denial of service via deeply nested HTML. During parsing, JustHTML.init always reaches TreeBuilder.finish, which unconditionally calls populateselectedcontent. That function recursively traverses the DOM via findelements / findelement without a depth bound,...

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...
CVE-2026-28394 OpenClaw < 2026.2.15 - Denial of Service via Unbounded Response Parsing in web_fetch Tool
OpenClaw versions prior to 2026.2.15 contain a denial of service vulnerability in the webfetch tool that allows attackers to crash the Gateway process through memory exhaustion by parsing oversized or deeply nested HTML responses. Remote attackers can social-engineer users into fetching malicious...
python: protobuf: Protobuf: Denial of Service due to recursion depth bypass
A flaw was found in protobuf. A remote attacker can exploit this denial-of-service DoS vulnerability by supplying deeply nested google.protobuf.Any messages to the google.protobuf.jsonformat.ParseDict function. This bypasses the intended recursion depth limit, leading to the exhaustion of Python’...
