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-2026-50193

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....
