GHSA-3M6Q-JJ5J-38C9 Oj: Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process. This is a denial of service reachable from untrusted JSON. Details Two-step chain in ext/oj/fast.c: 1. doceachchild line 1501 increments doc-where pas...

CVE-2026-49847 FreeSWITCH: Stack overflow in bundled cJSON parser via deeply nested JSON

CVE-2026-42358

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...

Uncontrolled Recursion

Overview Affected versions of this package are vulnerable to Uncontrolled Recursion through the Root.fromJSON or Namespace.addJSON functions. An attacker can cause resource exhaustion and disrupt service availability by submitting a crafted JSON descriptor with deeply nested namespace definitions...

CVE-2026-40612 jq: Stack overflow via unbounded recursion in jv_contains

jq is a command-line JSON processor. In 1.8.1 and earlier, jvcontains recurses into nested arrays/objects with no depth limit. With a sufficiently nested input structure built programmatically with reduce, since the JSON parser caps at depth 10000, the C stack is exhausted...
