- Summary
- Flextype CMS 0.9.9 through 1.0.0-alpha.3 Stored XSS via Plugin Directory
- Details
-
Flextype CMS versions 0.9.9 through 1.0.0-alpha.3 fail to HTML-escape plugin directory names in the dependency error page rendered by getValidPluginsDependencies(). Attackers with write access to the plugins directory can create a plugin with HTML characters in its name to execute arbitrary scripts in users' browsers when dependency validation fails.
