CVE-2023-7236 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Backup Bolt WordPress plugin, affecting versions <= 1.3.0. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview

The Backup Bolt plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.3.0 via error log file. This makes it possible for unauthenticated attackers to obtain information about an affected site's configuration, files and directories.

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, and no interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Backup Bolt <= 1.3.0 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Backup Bolt the fix is 1.4.0: builds <= 1.3.0 are affected, anything from 1.4.0 onward is not.

Remediation

Update to version 1.4.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Backup Bolt 1.4.0 closes this, and updating the plugin is the step that ends it.
