Description
Grav from 2.0.0 before 2.2.5 contains an improper access control vulnerability in FlexDirectory::dynamicFlexField() that allows page authors to call arbitrary Flex object methods via flex-*@ directives in page frontmatter. When a user with page edit rights opens the page, directives calling setStorageKey() and delete() run in their session, deleting protected pages neither account may delete.
