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.","affected":[{"package":{"name":"org.jolokia:jolokia-service-jsr160","ecosystem":"Maven","purl":"pkg:maven/org.jolokia/jolokia-service-jsr160"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.2"}]}],"versions":["2.0.0","2.0.0-M1","2.0.0-M2","2.0.0-M3","2.0.0-M4","2.0.1","2.0.2","2.0.3","2.1.0","2.1.1","2.1.2","2.2.0","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5","2.2.6","2.2.7","2.2.8","2.2.9","2.3.0","2.4.0","2.4.1","2.4.2","2.4.3","2.5.0","2.5.1","2.6.0","2.6.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-c9ff-59g8-m36q/GHSA-c9ff-59g8-m36q.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-84218"},{"type":"WEB","url":"https://github.com/jolokia/jolokia/issues/1049"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-84218"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2526752"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-c9ff-59g8-m36q"},{"type":"PACKAGE","url":"https://github.com/jolokia/jolokia"},{"type":"WEB","url":"https://jolokia.org/#jolokia_2_6_2_released_with_security_fixes"}],"database_specific":{"cwe_ids":["CWE-184"],"github_reviewed":true,"github_reviewed_at":"2026-10-07T18:04:11Z","nvd_published_at":"2026-09-01T14:17:49Z","severity":"HIGH"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
