The Drupal Anti-Spam by CleanTalk module, designed to protect your website from unwanted spam, has been found to have a security flaw. This vulnerability is a type of “Cross-site Scripting,” commonly known as XSS. Specifically, it’s a “Reflected XSS” issue. In simple terms, this means that a malicious script could be inserted into a web page through user input (like a search query or a link) and then “reflected” back to other users. If successful, this attack could trick a user’s browser into executing malicious code, potentially leading to unauthorized actions, disclosure of sensitive information, or defacement of the website. It’s a concern that requires attention from website administrators and developers using this module.
