CVE-2026-73195Network attack vector

Spreadsheet formula execution via unescaped CSV attributes

Published Sep 14, 2026 · Updated Sep 14, 2026

CSV formula injection in Apache Syncope allows remote authenticated users to place executable formulas in generated CSV exports. The CSV export path writes a user's plain-attribute value without neutralizing spreadsheet formula syntax, so the value remains active in an exported cell. Execution requires an authorized user to store the payload and a recipient to open the export in a spreadsheet application; the resulting formula runs in that application's context.
