Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.

CWE-94: Improper Control of Generation of Code ('Code Injection')

Reaching this weakness in WP All Import <= 3.6.7 takes a caller who can reach the endpoint. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.

The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. For WP All Import the fix is 3.6.8: builds <= 3.6.7 are affected, anything from 3.6.8 onward is not.

Remediation

Update to version 3.6.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP All Import: 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: WP All Import 3.6.8 closes this, and updating the plugin is the step that ends it.
