At a glance

CVE-2022-1037 is a high-severity Server-Side Request Forgery (SSRF) vulnerability in the EXMAGE WordPress plugin, affecting versions <= 1.0.6. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 1.0.7; sites on affected versions should update now. Disclosed April 2022, reported by Luan Pedersini.

Vulnerability Overview

The EXMAGE WordPress plugin before 1.0.7 does to ensure that images added via URLs are external images, which could lead to a blind SSRF issue by using local URLs

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 interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-918: Server-Side Request Forgery (SSRF)

Reaching this weakness in EXMAGE <= 1.0.6 takes a caller who can reach the endpoint. Server-side request forgery means the application fetches a URL supplied by the caller, turning the server into a proxy for requests the attacker could not make directly.

The request originates from inside the hosting network, which is how these flaws reach cloud metadata endpoints, internal admin panels and services that trust local traffic. For EXMAGE the fix is 1.0.7: builds <= 1.0.6 are affected, anything from 1.0.7 onward is not.

Remediation

Update to version 1.0.7, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to EXMAGE: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: EXMAGE 1.0.7 closes this, and updating the plugin is the step that ends it.
