Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Statamic CMS (Packagist statamic/cms) versions before 5.73.24 and versions from 6.0.0 before 6.20.1 are affected. Form submission values were not neutralized for spreadsheet formula characters when exported to CSV, so a value beginning with a character such as =, +, - or @ could run as a formula when a Control Panel user opens the export. An anonymous front-end visitor can supply the value, and it is triggered when an authorized user opens the export in a spreadsheet application, which affects that application rather than the Statamic server. Upgrade to 5.73.24 or 6.20.1.
