+Subject: [PATCH] Limit path depth to prevent stack overflow
+
+Deeply nested path arrays can cause unbounded recursion in
+`jv_setpath`, `jv_getpath`, and `jv_delpaths`, leading to
+stack overflow. Add a depth limit of 10000 to match the
+existing `tojson` depth limit. This fixes CVE-2026-33947.

+(cherry picked from commit fb59f1491058d58bdc3e8dd28f1773d1ac690a1f)
