At a glance

CVE-2024-0677 is a medium-severity Server-Side Request Forgery (SSRF) vulnerability in the Pz-LinkCard WordPress plugin, affecting versions <= 2.5.2. It carries a CVSS score of 5.0 (reachable over the network; low attack complexity). The issue is fixed in version 2.5.3; sites on affected versions should update now. Disclosed March 2024, reported by Dmitrii Ignatyev.

Vulnerability Overview

The Pz-LinkCard plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 2.5.2 via shortcode. This makes it possible for authenticated attackers, with contributor access or higher, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.

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.

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

Reaching this weakness in Pz-LinkCard <= 2.5.2 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 Pz-LinkCard the fix is 2.5.3: builds <= 2.5.2 are affected, anything from 2.5.3 onward is not.

Remediation

Update to version 2.5.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Pz-LinkCard: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Pz-LinkCard 2.5.3 closes this, and updating the plugin is the step that ends it.
