Yeah, this has come up already and keeps popping up because, WordFence...
It is a false positive in WordFence. You'll have to ignore it, there's nothing we can do, sadly (It's not even a PHP file).
The flagged file(s) just store cached data about plugins in the WordPress.org repository like their names, slugs, and homepages, and apparently WordFence doesn't like some of the URLs some plugins set as their homepage.
The last time I checked, the flagged URL looked completely legit and was from an active plugin in the repo.
Which one is flagged now?
