Vulnerability Title
jq: Unbounded Recursion in jv_setpath(), jv_getpath() and delpaths_sorted()
Vulnerability Description
jq is a command-line JSON processor. In versions 1.8.1 and below, functions jv_setpath(), jv_getpath(), and delpaths_sorted() in jq's src/jv_aux.c use unbounded recursion whose depth is controlled by the length of a caller-supplied path array, with no depth limit enforced. An attacker can supply a JSON document containing a flat array of ~65,000 integers (~200 KB) that, when used as a path argument by a trusted jq filter, exhausts the C call stack and crashes the process with a segmentation fault (SIGSEGV). This bypass works because the existing MAX_PARSING_DEPTH (10,000) limit only protects the JSON parser, not runtime path operations where arrays can be programmatically constructed to arbitrary lengths. The impact is denial of service (unrecoverable crash) affecting any application or service that processes untrusted JSON input through jq's setpath, getpath, or delpaths builtins. This issue has been addressed in commit fb59f1491058d58bdc3e8dd28f1773d1ac690a1f.

Vulnerability Title
jq 安全漏洞
Vulnerability Description
jq是jqlang开源的一个轻量级且灵活的命令行 JSON 处理器。 jq 1.8.1及之前版本存在安全漏洞，该漏洞源于jv_setpath、jv_getpath和delpaths_sorted函数使用无限制递归，可能导致拒绝服务攻击。
