CVE-2025-68568 identifies a missing authorization vulnerability in the integrationclaspo Popup Builder plugin, which is used to create exit-intent pop-ups, spin-the-wheel promotions, newsletter signups, email capture, and lead generation forms. The flaw arises from incorrectly configured access control security levels, allowing unauthenticated attackers to bypass authorization checks and perform unauthorized actions within the plugin. This can lead to unauthorized modification of popup content, form configurations, or lead capture mechanisms, potentially undermining the integrity of marketing campaigns or enabling injection of malicious content. The vulnerability affects all versions up to and including 1.0.5. The CVSS score is 7.5 (high), with an attack vector of network, no privileges required, no user interaction needed, and impact limited to integrity compromise without affecting confidentiality or availability. No patches or known exploits are currently reported. The vulnerability is significant because it allows remote attackers to manipulate website components that directly interact with users and collect sensitive data, which can have downstream effects on trust and data quality.

For European organizations, this vulnerability poses a risk primarily to the integrity of their web-based marketing and lead generation efforts. Unauthorized changes to pop-ups or forms can lead to misinformation, loss of leads, or injection of malicious content that could harm brand reputation and customer trust. While confidentiality and availability are not directly impacted, the integrity breach can facilitate phishing or social engineering attacks by altering user-facing content. Organizations relying heavily on digital marketing and customer engagement tools are particularly vulnerable. Disruption or manipulation of lead capture forms can also affect business operations and revenue. Additionally, regulatory compliance risks may arise if altered forms collect personal data improperly or mislead users, potentially violating GDPR requirements.

Organizations should monitor for updates from integrationclaspo and apply patches promptly once released. Until patches are available, restrict access to the plugin’s administrative interfaces using web application firewalls (WAFs) or IP whitelisting to prevent unauthorized remote access. Implement strict role-based access controls within content management systems to limit who can modify popup and form configurations. Regularly audit plugin settings and logs for unauthorized changes or suspicious activity. Consider temporarily disabling the plugin if it is not critical to operations. Employ security monitoring tools to detect anomalous behavior related to lead generation forms. Educate marketing and IT teams about the risks of unauthorized modifications and establish incident response plans to quickly address potential exploitation.
