Executive Summary

The MetaMagic SEO Plugin for WordPress has a vulnerability known as Cross-Site Request Forgery (CSRF) in all versions up to and including 1.6. This occurs because the plugin's metamagic_update_options function lacks proper nonce validation. As a result, an attacker who tricks a site administrator into clicking a malicious link can cause unauthorized changes to the plugin's SEO settings.

  • The attacker can enable or disable the plugin.
  • The attacker can toggle the output of description and keyword meta tags.
Impact Analysis

This vulnerability allows unauthenticated attackers to modify SEO settings of the MetaMagic SEO Plugin by tricking an administrator into performing an action. The impact includes unauthorized changes to SEO configurations which could affect website visibility and behavior.

  • Attackers can disable the SEO plugin, potentially reducing search engine optimization effectiveness.
  • Attackers can alter meta tag outputs, which may mislead search engines or users.
  • Since the vulnerability requires user interaction (UI:R), the risk depends on successful social engineering.
Mitigation Strategies

To mitigate this vulnerability, you should update the MetaMagic SEO Plugin to a version later than 1.6 where the nonce validation issue in the metamagic_update_options function is fixed.

Additionally, avoid clicking on suspicious links or performing actions from untrusted sources that could trigger forged requests.
