CVE-2024-24928

Vulnerability

Overview The Content Cards plugin for WordPress, developed by Arunas Liuiza, is vulnerable to Stored Cross-Site Scripting (XSS) in versions up to 0.9.7. The vulnerability arises from improper neutralization of user input during web page generation, allowing an attacker to inject arbitrary web scripts or HTML [1].

Exploitation

Conditions Exploitation requires a privileged user, such as an editor or administrator, to perform an action like clicking a malicious link or visiting a crafted page. Once initiated, the injected script is stored on the server and executed when other users access the affected page [1].

Impact

Successful exploitation enables an attacker to execute malicious scripts (e.g., redirects, advertisements, or other HTML payloads) in the context of the victim's browser. This can lead to defacement, phishing, or further compromise of the site and its visitors [1].

Mitigation

As of the advisory, no official patch has been released. It is recommended to update the plugin as soon as a patched version becomes available. In the interim, Patchstack has issued a mitigation rule to block attacks [1]. Users unable to update should consult their hosting provider or web developer for assistance.
