 "title": "wpDiscuz <= 7.6.73 - Unauthenticated Stored Cross-Site Scripting via Comment Author Name",
 "description": "The wpDiscuz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the comment author name in all versions up to, and including, 7.6.73. This is due to the comment walker filling comment templates with sequential str_replace() calls. A template placeholder such as {TEXT} in a commenter's name, which is printed in places like the avatar alt attribute, is expanded again into the comment's HTML, which breaks the attribute context. The reply-to author name is also output without escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user, including a moderator viewing a pending comment, accesses an affected page.",
