Received confusing email about security issues detected

I received a very confusing email from Jetpack about security issues having been detected on my website. The email included special characters, seemingly replacing what was likely once useful title information. I pasted the introductory part of the message below, which would probably have made sense if titles were in place of the characters; characters such as pike (|), pound (#), equal (=), and greater than (>). I am hoping the “Meta Slider plugin” was the only actual problem. I am already safe on that one. Although, it looks like two others were intended to be listed.
