CVE-2022-27858Network attack vector

Code execution via unneutralized CSV formulas

Published Nov 8, 2022 · Updated Apr 28, 2026

CSV injection in Elementor Activity Log 2.8.3 and earlier allows remote attackers to embed formulas in exported activity-log files. The CSV exporter writes untrusted activity-log fields as spreadsheet cells without neutralizing formula-leading characters. Code runs only when an administrator downloads the export and opens it in a spreadsheet configured to evaluate formulas.
