CVE-2025-68512 is a stored Cross-site Scripting (XSS) vulnerability found in the Real 3D FlipBook plugin developed by creativeinteractivemedia, affecting versions up to and including 4.11.4. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker with limited privileges (PR:L) to inject malicious scripts that are stored persistently and executed when other users view the affected content. The attack requires user interaction (UI:R), such as a victim visiting a maliciously crafted page, and can lead to a scope change (S:C), meaning the impact can extend beyond the initially compromised component. The CVSS 3.1 vector indicates network attack vector (AV:N), low attack complexity (AC:L), and limited privileges required, but user interaction is necessary. The impact affects confidentiality and integrity partially (C:L/I:L), but does not affect availability (A:N). Stored XSS can be leveraged to steal session cookies, perform actions on behalf of users, or deliver further malware payloads, potentially compromising user accounts or administrative functions. Although no known exploits are currently in the wild, the presence of this vulnerability in a widely used WordPress plugin makes it a notable risk for websites using this component to display interactive 3D flipbook content. The lack of an official patch link suggests that remediation may require vendor updates or manual mitigation steps.

For European organizations, this vulnerability poses a moderate risk primarily to websites using the Real 3D FlipBook plugin, particularly those that allow user-generated content or have multiple user roles with varying privileges. Exploitation could lead to unauthorized disclosure of sensitive information such as session tokens or personal data, and unauthorized modification of displayed content, undermining user trust and potentially leading to reputational damage. While availability is not impacted, the integrity and confidentiality breaches could facilitate further attacks like phishing or privilege escalation. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and e-commerce, could face compliance issues if exploited. The risk is heightened for public-facing websites with high traffic, increasing the likelihood of user interaction with malicious payloads. Given the medium severity and absence of known exploits, the threat is currently manageable but warrants proactive mitigation to prevent exploitation.

To mitigate CVE-2025-68512, European organizations should first verify if they use the Real 3D FlipBook plugin version 4.11.4 or earlier and plan immediate updates once a vendor patch is released. In the absence of an official patch, organizations should restrict the ability to submit or edit content to trusted users only, minimizing the risk of malicious input. Implement strict input validation and sanitization on all user-supplied data related to the plugin, employing server-side filtering to neutralize potentially harmful scripts. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. Regularly audit and monitor web application logs for unusual activities or injection attempts targeting the plugin. Additionally, educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content. Employ web application firewalls (WAF) with rules tailored to detect and block XSS payloads targeting this plugin. Finally, maintain an incident response plan to quickly address any detected exploitation attempts.
