  "title": "Canonical JSON key ordering flaw in Cpanel::JSON::XS",
  "summary": "Cpanel::JSON::XS versions 4.43 through 4.79 can produce inconsistent canonical JSON key ordering. An attacker able to influence hash keys may cause the same data to serialize differently across processes when UTF-8-flagged and byte-string keys are combined.",
  "mitigation": "Upgrade Cpanel::JSON::XS to version 4.80 or later. Until upgraded, avoid canonical encoding of hashes containing mixed UTF-8-flagged and byte-string keys from untrusted input.",
