At a glance
This record tracks a critical-severity Embedded Malicious Code vulnerability in the WowShipping Pro WordPress plugin, affecting versions < 1.0.8. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.0.8; sites on affected versions should update now. Disclosed April 2026.
Vulnerability Overview
The WowShipping Pro plugin for WordPress was injected with a backdoor in version 1.0.6. This is due to a supply chain compromise where an attacker was able to infect the copy of the plugin from the source. This makes it possible for attackers to remotely access victim WordPress instances completely infect the victim.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-506: Embedded Malicious Code
Reaching this weakness in WowShipping Pro < 1.0.8 takes a caller who can reach the endpoint. Embedded malicious code means functionality was deliberately placed in the software to act against the site owner's interest, rather than being an accidental defect.
Removing the software is not enough on its own — anything it created or modified while active has to be audited too. For WowShipping Pro the fix is 1.0.8: builds < 1.0.8 are affected, anything from 1.0.8 onward is not.
Remediation
Update to version 1.0.8, or a newer patched version
How does WordSec protect against this?
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: WowShipping Pro 1.0.8 closes this, and updating the plugin is the step that ends it.
