  "summary": "CVE-2026-47770 is fixed in jq on 1 platform, first by DEBIAN-CVE-2026-47770, released June 24, 2026. It is not reported as exploited. Patch Radar priority: Routine.",
  "title": "jq: jq is a command-line JSON processor",
  "description": "jq is a command-line JSON processor. Prior to 1.8.2, comparing two sufficiently deeply nested arrays with the == operator exhausts the C stack on jq\u0027s ordinary command-line surface, resulting in denial of service via stack exhaustion (uncontrolled recursion). The crash occurs in jq\u0027s recursive structural comparison code, with the recursion repeating through jvp_array_equal() and jv_equal() in src/jv.c when comparing deeply nested arrays; a nearby sort comparator path through jv_cmp() in src/jv_aux.c overflows the stack at a larger nesting depth from  the same missing recursion guard. Anyone running jq comparisons on attacker-controlled deeply nested JSON values, or embedding jq in a context  where untrusted data can reach the == comparison path, is affected. This vulnerability is fixed in 1.8.2.",
