jolokia-service-jsr160 Incomplete target JMX Service URL deny list handling for user-controlled input
CVE-2026-84218 · GHSA-c9ff-59g8-m36q
- Affected
- Maven org.jolokia:jolokia-service-jsr160 < 2.6.2
- Fixed in
- 2.6.2· Vendor fix available
- Issue
- A flaw was found in Jolokia's JSR-160 proxy functionality where insufficient validation of client-controlled JMX service URLs allows a bypass of the denylist introduced to mitigate CVE-2018-1000130. The proxy accepts a target.url value from a Jolokia POST request and passes it to JMXServiceURL and JMXConnectorFactory for establishing the remote JMX connection. The existing denylist only rejects URLs matching service:jmx:rmi:///jndi/ldap:., which can be bypassed using alternative valid JMX service URL forms, including ldaps:// schemes or LDAP URLs with a non-empty JMX host component. These URLs are accepted as valid JMXServiceURL objects and can cause the Jolokia agent JVM to perform a JNDI lookup against an attacker-controlled LDAP endpoint. This can result in server-side request forgery (SSRF), forwarding of supplied JMX credentials to the remote endpoint, and potentially remote code execution depending on the classes and configuration available in the target JVM.
Recommended action: Upgrade to 2.6.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
