Description: Webasyst Framework through 4.4.0 contains a stored cross-site scripting vulnerability in the Photos app that allows authenticated backend users to inject JavaScript via the album url parameter. Attackers with album edit rights can save a url value that breaks out of the unescaped attribute in DialogAlbumSettings.html, executing JavaScript in administrators' backend sessions.
