The generated HTML was rendered without passing through Drupal's filtering pipeline, so it relied on the LLM output being safe. Under certain circumstances a crafted prompt injection — planted in content that is included in the analysis — can cause the LLM to emit markup that results in stored Cross-site Scripting when the report is later viewed. This vulnerability is mitigated by the fact that an attacker must be able to inject text into the content that is sent to the LLM, and that prompt injection is non-deterministic and not guaranteed to succeed on a given attempt. Solution:  Install the latest version: * If you use the AI SEO/GEO Analyzer module 1.1.x, upgrade to ai_seo 1.1.3 [3] Reported By:  * Drew Webber (mcdruid) [4] of the Drupal Security Team Fixed By:  * Juhani Väätäjä (j-vee) [5] Coordinated By:  * Greg Knaddison (greggles) [6] of the Drupal Security Team * Drew Webber (mcdruid) [7] of the Drupal Security Team Security issue: https://git.drupalcode.org/security/185231-ai_seo-security/-/work_items/1 [8] ------------------------------------------------------------------------------ Contribution record [9] [1] https://www.drupal.org/project/ai_seo [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/ai_seo/releases/1.1.3 [4] https://www.drupal.org/u/mcdruid [5] https://www.drupal.org/u/j-vee [6] https://www.drupal.org/u/greggles [7] https://www.drupal.org/u/mcdruid [8] https://git.drupalcode.org/security/185231-ai_seo-security/-/work_items/1 [9] https://new.drupal.org/contribution-record?source_link=https%3A//www.drupal....
