How does WordSec protect against this?

The attempt arrives as an ordinary request to Media Library Assistant: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Media Library Assistant 2.82 closes this, and updating the plugin is the step that ends it.
