CVE-2023-6444 Scanner

Seriously Simple Podcasting is a popular WordPress plugin used by podcasters to manage and distribute their podcast episodes. It is widely utilized by both individual podcasters and organizations to simplify the podcasting process within WordPress. The plugin integrates with various podcast directories and platforms, providing a seamless experience for publishing and managing content. With its extensive customization options, users can tailor their podcast feeds to match their specific needs. However, vulnerabilities in the plugin can lead to potential security risks if not properly managed.

The vulnerability in the Seriously Simple Podcasting plugin allows for the unauthorized disclosure of sensitive information. Specifically, it exposes the podcast owner's email address through a crafted request. This issue is significant because the exposed email address is often the admin email, potentially leading to further security risks. The vulnerability is present in versions of the plugin prior to 3.0.0.

The vulnerability is triggered when an unauthenticated user sends a specially crafted request to the podcast feed endpoint. The plugin's response includes the podcast owner's email address within the XML feed, which is not properly secured. This vulnerability is particularly concerning because it does not require authentication, making it easy for attackers to exploit. The endpoint /feed/itunes is especially vulnerable, as it includes the <itunes:email> tag in its response, exposing the email address without any protective measures.

If exploited, this vulnerability could lead to the exposure of the podcast owner's email address, which is often the admin email. This information disclosure could allow attackers to target the admin with phishing attacks or other forms of social engineering. Additionally, the exposed email could be used in further attacks to gain unauthorized access to the WordPress site or associated accounts. The vulnerability may also erode the trust of users who rely on the privacy of their personal information.
