CVE-2024-29915 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Podlove Podcast Publisher WordPress plugin, affecting versions <= 4.0.9. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 4.0.10; sites on affected versions should update now. Disclosed March 2024, reported by Dimas Maulana.

Vulnerability Overview

The Podlove Podcast Publisher plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 4.0.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Podlove Podcast Publisher <= 4.0.9 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Podlove Podcast Publisher the fix is 4.0.10: builds <= 4.0.9 are affected, anything from 4.0.10 onward is not.

Remediation

Update to version 4.0.10, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Podlove Podcast Publisher: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Podlove Podcast Publisher 4.0.10 closes this, and updating the plugin is the step that ends it.
