CVE-2026-87367

A flaw was found in the JAXP (Java API for XML Processing) component of OpenJDK. An unauthenticated remote attacker can exploit this vulnerability by providing crafted input to applications or web services that process data through JAXP APIs. Successful exploitation allows the attacker to perform unauthorized data modifications, including updating, inserting, or deleting accessible data.

This vulnerability is rated as Low severity because successful exploitation requires high complexity and specially constructed input to JAXP template processing APIs, resulting in limited integrity impact without compromising confidentiality or service availability. In Red Hat Enterprise Linux and containerized OpenJDK environments, exposure is restricted to applications that accept untrusted XML or template data without adequate validation. General Java workloads that do not parse external template content remain unaffected.
