What is CVE-2026-44911?
CVE-2026-44911 is a low-severity missing authorization vulnerability in Apache Nifi, published on 22 Jun 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Authorization handling for component configuration verification requests in Apache NiFi 1.15.0 through 2.9.0 allows clients with read access to submit proposed configuration properties. The proposed properties override current configuration, enabling users with read access to invoke predefined verification methods with alternative settings. Apache NiFi installations that do not implement different levels of authorization for viewing and modifying component configuration are not subject to this vulnerability. Upgrading to Apache NiFi 2.10.0 is the recommended mitigation, requiring write access to submit configuration verification requests.
Weakness: CWE-863
