We currently run a check once a day against all of the production dependencies that are deployed in mediawiki/vendor. I propose that in addition to that, we start checking on every commit whether there are any security issues for both production dependencies and development dependencies. At least two of our dev dependencies (codesniffer and phpunit) have had security issues in the past.
This task should be made public once T180231 is disclosed.
