CVE-2026-68980: Apache NiFi: Authorization Bypass for Parameter Context Asset Deletion

[David Handermann <exceptionfactory () apache org>]

Severity: Low 

Affected versions:

- Apache NiFi (org.apache.nifi:nifi-web-api) 2.0.0 through 2.10.0

Description:

Apache NiFi 2.0.0 through 2.10.0 support creating, reading, and deleting Assets associated with Parameter Contexts 
through the REST API. The framework authorizes asset deletion against the owning Parameter Context using the supplied 
Parameter Context Identifier and Asset Identifier. The framework performed authorized based on the supplied Parameter 
Context Identifier without verifying the requested Identifier against the stored Identifier. Apache NiFi installations 
that do not implement different levels of authorization across Parameter Contexts are not subject to this 
vulnerability, because the framework enforces write permissions as the security boundary. Upgrading to Apache NiFi 
2.11.0 is the recommended mitigation, which verifies Parameter Context ownership of the requested Asset before deletion 
using the same strategy applied to Asset read operations.

This issue is being tracked as NIFI-16154
