At a glance

CVE-2023-4274 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the WPvivid WordPress plugin, affecting versions 0.9.89. It carries a CVSS score of 8.7 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 0.9.90; sites on affected versions should update now. Disclosed September 2023, reported by Ivan Kuzymchak.

Vulnerability Overview

The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 0.9.89. This allows authenticated attackers with administrative privileges to delete the contents of arbitrary directories on the server, which can be a critical issue in a shared environments.

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 integrity, availability.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in WPvivid 0.9.89 takes an account at Administrator level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For WPvivid the fix is 0.9.90: builds 0.9.89 are affected, anything from 0.9.90 onward is not.

Remediation

Update to version 0.9.90, 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: WPvivid 0.9.90 closes this, and updating the plugin is the step that ends it.
