A JSON integer there is dereferenced as a pointer.\n\nUntrusted JSON decoded with relaxed and dupkeys_as_arrayref can crash the process or dereference an address chosen by a JSON number.","published":"2026-10-19T19:17:21.000Z","lastModified":"2026-10-19T20:50:18.000Z","status":"Awaiting Analysis","sourceIdentifier":"9b29abf9-4ab0-4765-b253-1875cd9b441e","cvss":null,"cwe":["CWE-176","CWE-843"],"affected":[],"epss":{"score":0.00199,"percentile":0.09683,"date":"2026-10-27","history":[{"date":"2026-10-20","score":0.00199,"percentile":0.09196}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
