CVE-2026-67216

A flaw was found in cJSON. An inefficient algorithmic complexity flaw in the cJSONCompare function allows a remote attacker to cause a denial of service DoS. By providing specially crafted, deeply nested JSON JavaScript Object Notation objects for comparison, an attacker can consume excessive CPU...

CVE-2026-67216 cJSON cJSON_Compare Exponential Complexity Denial of Service

cJSON through 1.7.19 contains an inefficient algorithmic complexity flaw in cJSONCompare. When comparing objects, the function recurses into each shared subtree twice, once in each direction, with no depth guard, making the running time exponential in nesting depth. A small, deeply nested documen...

cJSON through 1.7.19 contains an inefficient algorithmic complexity flaw in cJSON Compare. When comparing objects, the function recurses into each shared subtree twice, once in each direction, with no depth guard, making the running time exponential in nesting depth. A small, deeply nested docume...

CVE-2026-13064

Certain query operations involving deeply nested $jsonSchema constructs can trigger disproportionate CPU consumption in affected MongoDB deployments, potentially leading to resource exhaustion. The resulting CPU-bound operation cannot be interrupted through standard administrative controls...

PYSEC-2026-2343 Apache Airflow Vulnerable to Exposure of Sensitive Information to an Unauthorized Actor

A bug in Apache Airflow's Variable response masker caused nested-key redaction triggered by secret-suffixed key names like password, token, secret, apikey to be bypassed when the JSON value's nesting depth exceeded the shared secrets masker's recursion limit: the masker returned the original nest...

PYSEC-2026-1559 LlamaIndex vulnerable to DoS attack through uncontrolled recursive JSON parsing

The JSONReader in run-llama/llamaindex versions 0.12.28 is vulnerable to a stack overflow due to uncontrolled recursive JSON parsing. This vulnerability allows attackers to trigger a Denial of Service DoS by submitting deeply nested JSON structures, leading to a RecursionError and crashing...

CVE-2026-54592

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.3, Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process, leading to DoS. In a two-step chain in...

CVE-2026-50193

A flaw was found in jackson-databind, a general-purpose data-binding library for Jackson Data Processor. A remote attacker can exploit this vulnerability by sending deeply nested JSON JavaScript Object Notation data to a service that reads and processes it. This can lead to a Denial of Service Do...

CVE-2026-47770 jq: stack overflow in deep structural equality

jq is a command-line JSON processor. Prior to 1.8.2, comparing two sufficiently deeply nested arrays with the == operator exhausts the C stack on jq's ordinary command-line surface, resulting in denial of service via stack exhaustion uncontrolled recursion. The crash occurs in jq's recursive...

CVE-2026-50193

jackson-databind contains a DoS in JSON tree handling: if a service reads deeply nested JSON (1000s of levels) via ObjectMapper.readTree() and then writes that JsonNode with toString(), it can consume significant resources. Affected are 2.13.0–2.14.0; fixed in 2.14.0. Mitigation: upgrade to 2.14....
