Attack-Flow Graph

Compliance Impact

The vulnerability allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts via stored cross-site scripting (XSS). This can lead to unauthorized access to user data or session hijacking, which may result in violations of data protection regulations such as GDPR or HIPAA that require safeguarding personal and sensitive information.

Specifically, the exploitation of this vulnerability could compromise the confidentiality and integrity of user data, potentially leading to non-compliance with standards that mandate protection against unauthorized data access and data breaches.

Executive Summary

The Blubrry PowerPress plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its 'powerpress' and 'podcast' shortcodes in versions up to and including 11.15.15.

This vulnerability exists because the plugin does not properly sanitize input or escape output, allowing authenticated users with contributor-level access or higher to inject malicious web scripts.

These injected scripts execute whenever any user accesses the affected page, potentially compromising user security.

Impact Analysis

This vulnerability can allow attackers with contributor-level access or above to inject malicious scripts into pages.

When other users visit these pages, the malicious scripts execute in their browsers, which can lead to theft of sensitive information, session hijacking, or other malicious actions.

The CVSS score of 6.4 indicates a medium severity impact, with potential confidentiality and integrity loss but no impact on availability.
