At a glance

CVE-2023-23678 is a medium-severity Improper Neutralization of Formula Elements in a CSV File vulnerability in the WPLP Cookie Consent WordPress plugin, affecting versions <= 2.2.5. It carries a CVSS score of 6.4 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 2.2.6; sites on affected versions should update now. Disclosed June 2023, reported by Rio Darmawan.

Vulnerability Overview

The WP Cookie Notice for GDPR, CCPA & ePrivacy Consent plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 2.2.5. This allows authenticated administrators to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

Technical Analysis

The vector marks this flaw as remotely reachable over the network. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-1236: Improper Neutralization of Formula Elements in a CSV File

The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.

Remediation

Update to version 2.2.6, or a newer patched version

How does WordSec protect against this?

An attacker needs Administrator access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WPLP Cookie Consent 2.2.6 closes this, and updating the plugin is the step that ends it.
