CVE-2026-86089: Apache NiFi: Missing Process Group Authorization for Connector Migration

Apache NiFi 2.11.0 Connector Migration REST APIs authorize only against the target Connector, skipping Process Group access checks (CVE-2026-86089, Low).

Apache NiFi 2.11.0 supports migrating version-controlled Process Group contents into a Connector via REST API methods that list eligible migration sources and submit migration requests. Both methods were authorized only against the target Connector, without evaluating user access to the involved Process Groups. The flaw, tracked as CVE-2026-86089, is rated Low severity and affects the nifi-web-api component.

CVE-2026-82561: Apache NiFi: Missing Authorization for Components Referenced in Flow Update Methods

Apache NiFi 1.5.0-2.11.0 flow update REST methods lack authorization checks for referenced components, permitting unauthorized Process Group flow replacement (CVE-2026-82561).

Apache NiFi 1.5.0 through 2.11.0 expose REST API methods that replace the entire contents of a Process Group with a client-supplied flow definition, including versioned flow update and rebase operations. Framework authorization for these methods was limited to read and write privileges on the target Process Group, without checking components referenced in the flow (CVE-2026-82561). No severity rating was provided in the disclosure; the affected version range is broad.

CVE-2026-81866: Apache NiFi: Missing Authorization for Assets and Secrets Referenced by Connector Configuration

Apache NiFi 2.9.0-2.11.0 Connector configuration update and verification APIs skip authorization for referenced Assets and Secrets (CVE-2026-81866, Low).

Apache NiFi 2.9.0 through 2.11.0 provide Connector configuration update and verification REST API methods that do not enforce authorization checks on Assets and Secrets referenced in the proposed configuration. Updating or verifying a Connector configuration can apply Asset and Secret references without the caller holding the required privileges. The issue, CVE-2026-81866, is rated Low severity and affects the nifi-web-api component.

CVE-2026-70469: Apache NiFi: Improper Handling of Case Sensitivity for Content-Encoding in HTTP Requests

Apache NiFi CVE-2026-70469: duplicate or non-standard Content-Encoding headers bypass gzip request filtering in NiFi 2.11.0's REST API.

Apache NiFi disclosed CVE-2026-70469, rated High, affecting the Jetty-based REST API module (org.apache.nifi:nifi-jetty) in version 2.11.0. NiFi 2.11.0 disabled gzip-encoded HTTP requests and rejects those carrying the standard Content-Encoding header, but the framework enforcement filter fails to check multiple instances of the header and does not reject non-standard gzip identifiers, allowing crafted requests to evade the check. The disclosure was posted to oss-security by David Handermann.
