Pimcore admin-ui-classic-bundle provides a Backend UI for Pimcore. The translation value with text including “%s” (from “%suggest%) is parsed by sprintf() even though it’s supposed to be output literally to the user. The translations may be accessible by a user with comparatively lower overall access (as the translation permission cannot be scoped to certain “modules”) and a skilled attacker might be able to exploit the parsing of the translation string in the dialog box.

This issue has been patched in commit abd77392 which is included in release 1.1.2. Users are advised to update to version 1.1.2 or apply the patch manually.
