CVE-2023-0070: ResponsiveVoice Text To Speech < 1.7.7 - Contributor+ Stored XSS

The ResponsiveVoice Text To Speech WordPress plugin before 1.7.7 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

Security readout for executives and security teams

Plain-English summary

This affects WordPress sites using ResponsiveVoice Text To Speech before 1.7.7. A logged-in user with Contributor-level access or higher could store malicious script through plugin shortcode attributes, affecting later viewers of the page or post.

Executive priority

Prioritize patching on WordPress sites with multiple content contributors. Business risk is moderate: compromise requires authenticated content access, but stored XSS can affect later visitors or administrators.

Technical view

The plugin failed to validate and escape some shortcode attributes before rendering them in embedded content. The CVSS 3.1 score is 5.4: network reachable, low attack complexity, low privileges required, user interaction required, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress environments running ResponsiveVoice Text To Speech before 1.7.7, especially sites allowing Contributor or higher users to create or edit shortcode content.

Exploitation context

The source bundle references WPScan with an exploit tag, but KEV is false and no provided source states active exploitation. Treat this as publicly documented, not confirmed actively exploited.

Researcher notes

The key condition is shortcode attribute output without adequate validation and escaping. Validate by version and by reviewing role access to affected content paths. Evidence does not support claims of active exploitation.

Mitigation direction

  • Update ResponsiveVoice Text To Speech to version 1.7.7 or later.
  • Restrict Contributor and higher content-editing access until patched.
  • Review pages and posts containing ResponsiveVoice shortcodes.
  • Check vendor and WPScan guidance for any additional remediation notes.

Validation and detection

  • Inventory WordPress sites for the ResponsiveVoice Text To Speech plugin.
  • Confirm installed plugin versions are 1.7.7 or later.
  • Review user roles able to create or edit shortcode content.
  • Inspect recent shortcode-bearing posts for unexpected attributes or script content.

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

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
