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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-184"],"references":["https://access.redhat.com/security/cve/CVE-2026-84218","https://bugzilla.redhat.com/show_bug.cgi?id=2526752","https://github.com/advisories/GHSA-c9ff-59g8-m36q","https://github.com/jolokia/jolokia/issues/1049","https://jolokia.org/#jolokia_2_6_2_released_with_security_fixes"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-84218","score":0.00949,"percentile":0.61219,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c9ff-59g8-m36q","url":"https://osv.dev/vulnerability/GHSA-c9ff-59g8-m36q","summary":"jolokia-service-jsr160 Incomplete target JMX Service URL deny list handling for user-controlled input","modified":"2026-10-07T18:15:10.799001851Z","packages":[{"ecosystem":"Maven","name":"org.jolokia:jolokia-service-jsr160","purl":"pkg:maven/org.jolokia/jolokia-service-jsr160","ranges":["<2.6.2"],"fixed":["2.6.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
