At a glance

CVE-2026-1785 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Code Snippets WordPress plugin, affecting versions <= 3.9.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.9.5; sites on affected versions should update now. Disclosed February 2026, reported by type5afe.

Vulnerability Overview

The Code Snippets plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.9.4. This is due to missing nonce validation on the cloud snippet download and update actions in the Cloud_Search_List_Table class. This makes it possible for unauthenticated attackers to force logged-in administrators to download or update cloud snippets without their consent via a crafted request, granted they can trick an administrator into visiting a malicious page.

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.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Code Snippets <= 3.9.4 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Code Snippets the fix is 3.9.5: builds <= 3.9.4 are affected, anything from 3.9.5 onward is not.

Remediation

Update to version 3.9.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Code Snippets: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Code Snippets 3.9.5 closes this, and updating the plugin is the step that ends it.
