Spreadsheet formula injection via unneutralized ticket values
Published Jan 16, 2026 · Updated Jan 16, 2026
CSV injection in Best Practical Request Tracker before 4.4.9, 5.0.9, and 6.0.2 allows attackers to alter spreadsheet data via TSV exports. The search-results TSV exporter writes ticket values beginning with spreadsheet formula-control characters without neutralizing them. High-privileged access is required to exploit the export path, and a recipient must open the TSV in a spreadsheet; further execution effects are not publicly detailed.
