I wanted to share this extension attribute that seems to work for capturing the Zoom client version installed on a machine in absence of any patch management. Took some examples from other software version reporting examples and was able to figure out where the version number lived. This may work for other Apps installed by pulling the CFBundleVersion from the info.plist located in the Applications content folder.
#!/bin/sh
#Check to see if Zoom client is installed and if true, what is the version
if [ -d /Applications/zoom.us.app ]; then
ZoomVersion=$( sudo defaults read /Applications/zoom.us.app/Contents/info.plist CFBundleVersion )
echo "<result>$ZoomVersion</result>"
else
echo "<result>Not installed</result>"
fi
