  "title": "Unbounded property-name memory use in Jackson Smile parser",
  "summary": "The Smile parser in jackson-dataformats-binary does not enforce the configured limit for object property-name length. An attacker who can submit Smile data to an application that parses it can exhaust memory and disrupt service, particularly when document-size limits are not configured.",
  "mitigation": "Set a finite document-size limit and enforce request or upload size limits before Smile parsing. Do not accept untrusted Smile input where it is not required; the evidence does not identify a fixed release.",
