CVE-2026-18140

A flaw was found in aws-smithy-json. This vulnerability allows a remote, unauthenticated attacker to cause a denial of service DoS in smithy-rs generated servers. By sending a small HTTP request containing deeply nested JSON, the attacker can trigger uncontrolled recursion in the aws-smithy-json...

CVE-2026-74039

Wazuh 4.0.0 before 4.14.7 and 5.0.0-beta2 are vulnerable to CPU-exhaustion DoS. Authenticated attackers with allow_run_as enabled can submit arbitrarily deeply nested auth_context JSON to POST /security/user/authenticate/run_as, causing the API framework to consume excessive CPU and deny service ...

jackson-databind: Jackson-databind: Denial of Service via deeply nested JSON processing

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...

PT-2026-66566

Name of the Vulnerable Software and Affected Versions aws-smithy-json versions prior to 0.62.7 Description Uncontrolled recursion occurs in the unknown-key skip path of the runtime crate, which is invoked by the smithy-rs code generator from every generated struct deserializer. This allows remote...

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...

PT-2026-65814

Name of the Vulnerable Software and Affected Versions cJSON versions prior to 1.7.20 Description An inefficient algorithmic complexity flaw exists in the cJSON Compare function. When comparing objects, the function recurses into each shared subtree twice without a depth guard, resulting in...

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...

Amazon Linux 2023 : jackson-databind (ALAS2023-2026-1949)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1949 advisory. jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends...

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

A flaw was found in Oj, a Ruby gem for JSON parsing. A remote attacker can exploit this vulnerability by providing a deeply nested JSON document. This can lead to a stack buffer overflow in the Oj::Doceachchild function, causing the process to abort and resulting in a denial of service DoS for th...

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...
