CVE-2026-44913: Apache NiFi: Improper Escaping of Table Names in CaptureChangeMySQL

• Severity: high (CVSS 7.2 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-22 · updated 2026-10-25
• Weakness: CWE-116

Description

Improper escaping of database table names in the CaptureChangeMySQL Processor included with Apache NiFi 1.2.0 through 2.9.0 allows for injecting SQL commands using crafted naming. Manual quoted boundaries added in Apache NiFi 1.8.0 narrowed the scope of potential injection options, but did not cover additional strategies. Apache NiFi installations that do not use the CaptureChangeMySQL Processor are not subject to this vulnerability. Upgrading to Apache NiFi 2.10.0 is the recommended mitigation, which incorporates more robust identifier escaping.

Affected products

• Apache Software Foundation Apache NiFi: from 1.2.0 before 2.10.0 — fixed in 2.10.0

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache NiFi 2.10.0. Check the vendor advisory for mitigations.
