Subject: CVE-2026-44913: Apache NiFi: Improper Escaping of Table Names in
CaptureChangeMySQL
Severity:
Affected versions:
- Apache NiFi (org.apache.nifi:nifi-cdc-mysql-processors) 1.2.0 through 2.9.0
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.
This issue is being tracked as NIFI-15905
