Malformed UTF-8, control bytes and backslashes reach the decoded hash, while malformed UTF-8 and control bytes in a quoted key or a value are rejected.\n\nLater operations on the key, including lc, uc or encoding the hash again, die with a malformed UTF-8 error.","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-1286"],"affected":[],"epss":{"score":0.00171,"percentile":0.0647,"date":"2026-10-26","history":[{"date":"2026-10-20","score":0.00171,"percentile":0.06117}]},"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.
