Hi, The following vulnerability was published for ujson. CVE-2026-54911[0]: | UltraJSON is a fast JSON encoder and decoder written in pure C with | bindings for Python 3.7+. Prior to 5.13.0, ujson.dumps() (or | ujson.dump() or ujson.encode()) have a reject_bytes=False option. | When set, they may accept malformed or truncated UTF-8 byte | sequences, silently rewriting them into different Unicode characters | instead of rejecting them. This leads to input validation bypass and | data integrity issues. This vulnerability is fixed in 5.13.0. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
