CVE-2026-44913Network attack vector

SQL injection via improperly escaped table names

Published Jun 22, 2026 · Updated Jun 22, 2026

SQL injection in CaptureChangeMySQL in Apache NiFi 1.2.0 through 2.9.0 allows remote authenticated users to inject SQL via crafted table names. Table-information queries applied manual quoted boundaries to separate schema and table identifiers instead of standardized escaping of a qualified name. Exploitation requires CaptureChangeMySQL and privileged interaction with attacker-controlled MySQL identifiers, enabling injected SQL against the connected database.
