Krusader 1.50-beta1 up to 1.70.0 stores passwords for remote connections in cleartext in the bookmark file (krbookmarks.xml), which allows attackers to steal passwords by obtaining the file.
The Popular URL capability (popularurls.cpp) in Krusader 1.60.0 and 1.70.0-beta1 saves passwords in cleartext in the krusaderrc file when the user enters URLs containing passwords in the panel URL field, which might allow attackers to access other sites.
