CVE-2023-49145: Apache Nifi

Medium severity, CVSS 5.4. EPSS: 1.2% chance of exploitation in the next 30 days.

Apache NiFi 0.7.0 through 1.23.2 include the JoltTransformJSON Processor, which provides an advanced configuration user interface that is vulnerable to DOM-based cross-site scripting. If an authenticated user, who is authorized to configure a JoltTransformJSON Processor, visits a crafted URL, then arbitrary JavaScript code can be executed within the session context of the authenticated user. Upgrading to Apache NiFi 1.24.0 or 2.0.0-M1 is the recommended mitigation.

Affected products

• Apache Nifi: from 0.7.0, before 1.24.0 (fixed in 1.24.0)
