Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The jackson-databind package, versions 2.10.0 up to but not including 2.14.0, is vulnerable to a denial of service. An attacker who can send deeply nested JSON to a service that parses it as a JsonNode and then calls JsonNode.toString() on that node can trigger a StackOverflowError, consuming significant resources with relatively small requests. Upgrade to version 2.14.0 or later. As a workaround, serialize JsonNode with ObjectMapper.writeValueAsString(node) instead of toString().
