Adobe only updates current versions of Lightroom and support for the Canon EF-S 10-18mm f/4.5-5.6 IS STM lens was added in Lightroom v5.6
Unless someone creates a profile using the Adobe Lens Profile Creator and uploads it for you to download using the Adobe Lens Profile Downloader it wont happen.
You have 2 options, either download and use the latest DNG Convertor and import those files into your version or upgrade to v 5.

How will that help, Don? Still no Canon 10-18mm lens profile in Lr 4.
There is another alternative. If you only want new lens profiles, and those lens profiles are supplied as external profile (.dcp) files, then you can install the latest DNG Converter, which will install the latest lens profiles to the Photoshop location which is not shared with LR, then copy the lens profiles you’re interested into over to a third place, the user-contributed lens profile location in your Users library, and LR will see them, there.
You probably have a mirrorless camera which Adobe corrects lens distortions for automatically. The DNG contains raw data that is untouched, but the preview is corrected, so the other programs use the preview JPG?
Hi BKKDon, thanks for the info about the no updating of LR4
Hi ssprengel, I did start this thread but you have rather lost me.
My first problem is that I have no idea why this problem has anything to do with DNG. I know we can convert a photo to DNG using LR's Library function but is this the DNG converter that you are talking about or something different?
Anyway, where would I find the latest version of the DNG converter, where is this file that the Install would write the latest lens profiles to and where is the file that I should then copy this to.
Sorry but I seem to be on a different planet.
Am I a lost cause or can you explain a little more?
What OS do you have?
My apologies I assumed that it would apply the lens corrections as it does in this case
Well, you live and learn - I didn't realise that.
I have a similar Windows version so I can give you specific instructions. This is how to copy the lens profile for the 10-18 from the Adobe PS location to the Users location so an older LR can see it.
Download and install the DNG Converter 8.7 from: http://www.adobe.com/downloads/updates/ This will put the new profiles at a known location.
Find the profile you want to copy under C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\Canon and right-click Copy
I think the file you want is: Canon EOS 50D (Canon EF-S 10-18mm f4.5-5.6 IS STM) - RAW.lcp
Go to the Users profile location: C:\Users\Steve\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\Downloaded
You may need to create some of the folder path, but down through Roaming should exist. The AppData folder is hidden so you may have to type it into Explorer and hit Enter to get down into it, or type %AppData% into an Explorer address bar and hit Enter and you should be down into the Roaming folder.
Once you are in the Downloaded folder (that you may have had to create) do a Paste to copy the profile over to it, and you're done, once you've restarted LR so it'll see the new profile.
No the other programs I have use dcraw.
You are right about the mirrorless camera but I think what has happened here is that Sony includes a embedded lens profile. How it is applied, either in the DNG as corrected RAW data or as a conversion trigger, I don't know, but I have noticed that using dcraw and libraw the lens correction is applied so I suspect the RAW data is corrected.
Many thanks, ssprengel
Your instructions worked a treat. On opening LR4 subsequently, the 10-18mm lens correction was there and seems to work really well.
