CVE-2025-51735Network attack vector

Unauthenticated service interruption

Published Nov 28, 2025 · Updated Nov 28, 2025

CSV formula injection in HCL Software Unica 12.0.0 allows remote attackers to interrupt the service via unspecified vectors. The public advisory does not identify the CSV import or export path, the responsible code locus, or how formula-leading fields escape neutralization. CISA assesses network reachability without privileges or user interaction and bounds the reported consequence to availability loss.
