Backdrop CMS version 1.23.0 contains a stored cross-site scripting (XSS) vulnerability that can be exploited through the 'Card' content feature. This flaw allows an attacker to inject malicious scripts into user content, which could then be executed in the context of another user's browser. If successfully executed, it could lead to unauthorized actions or data theft. Website administrators should upgrade to the latest version to mitigate these risks and enhance the overall security of their applications.
