CVE-2026-44672Network attack vector

Unauthenticated code execution via dynamic-table columns

Published May 28, 2026 · Updated May 28, 2026

Code injection in affected MapFish Print branches allows remote attackers to execute arbitrary code through dynamic tables. TableProcessor places attacker-controlled column names into generated JasperReports field declarations and header expressions without neutralizing Java-expression syntax before compilation. No authentication or user interaction is required; affected ranges are 3.23.0 through 3.28.27, 3.29.0 through 3.30.29, 3.31.0 through 3.31.20, 3.32.0 through 3.33.13, and 3.34.0 through 4.0.2.
