Analysis

Technical impact

Improper Neutralization of Input During Web Page Generation (CWE‑79) in Drupal Anti‑Spam by CleanTalk allows reflected cross‑site scripting. This vulnerability can potentially allow malicious scripts to be executed in a victim's browser when input is reflected without proper sanitization.

All installations of the Drupal Anti‑Spam by CleanTalk module from version 0.0.0 through 9.7.1 are affected. Any Drupal site using this module is potentially at risk.

Risk and Exploitability
