Horde Mnemo Application Parent Frame Page Title XSS
Remote / Network Access
Loss of Integrity
Horde Mnemo contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate user-supplied input upon submission to the parent frame's page title. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Upgrade to version 1.1.4 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
