I have a client who has just informed us that they need to host .sls files on their WordPress website and that these should be available as downloads to logged-in members.
Ignoring the technicalities of enabling WordPress to accept the .sls file as uploads via the Media Gallery, is it safe to upload these files and have them available as downloable links on a website?
There appears to be little info about this files type, although various sites refer to them as simple text files wheras at least one resource says that sls files "can aggressively manipulate files on a system".
Any info / recommendations would be appreciated.
P.s. By 'safe' I mean, could these files be executed online and any damage caused to the server /site?
