What is CVE-2026-44913?
CVE-2026-44913 is a medium-severity SQL injection vulnerability in Apache Nifi, published on 22 Jun 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official 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.
Weakness: CWE-116
