CVE-2026-39816: apache nifi

csirt@kutim:~/threat-intel/cve/CVE-2026-39816

CVSS 8.8 · High EPSS 0,89%

Kerentanan Missing Authorization pada apache nifi. Skor CVSS 3.1 8.8 (High) menurut NVD.

Deskripsi (NVD)

The optional extension component TinkerpopClientService is missing the Restricted annotation with the Execute Code Required Permission in Apache NiFi 2.0.0-M1 through 2.8.0. The TinkerpopClientService supports configuration of ByteCode Submission for the Script Submission Type, enabling Groovy Script execution in the service prior to submitting the query. The missing Restricted annotation allows users without the Execute Code Permission to configure the Service in installations that use fine-grained authorization and have the optional TinkerpopClientService installed. Apache NiFi installations that do not have the nifi-other-graph-services-nar installed are not subject to this vulnerability. Upgrading to Apache NiFi 2.9.0 is the recommended mitigation.
