Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: CVE-2026-50193)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in JsonNode.toString() when serializing deeply nested JsonNode content created from user-supplied JSON. A remote attacker can send deeply nested JSON input to cause a denial of service.

Exploitation requires the service to read the input as JsonNode using ObjectMapper.readTree() and then serialize the same or modified node using JsonNode.toString().
