CVE-2025-50572Public exploitNetwork attack vector

Code execution via unescaped CSV formulas

Published Jul 31, 2025 · Updated Jul 5, 2026

CSV formula injection in Archer 6.11.00204.10014 allows remote attackers to execute code when a user opens an exported CSV file. User-controlled Device Name and other form values are written to CSV cells without neutralizing a leading equals sign, so a compatible spreadsheet interprets the value as a formula and invokes its command handler. Exploitation requires a user to export and open the poisoned record in a formula-capable spreadsheet; Archer disputes that this behavior is a vulnerability in its product.
