CVE-2025-67621 is a vulnerability identified in the 10up Eight Day Week Print Workflow plugin, specifically affecting versions up to and including 1.2.5. The flaw allows unauthorized users to retrieve embedded sensitive system information, which could include configuration details, credentials, or other confidential data embedded within the print workflow system. This exposure occurs because the plugin fails to adequately restrict access to sensitive data retrieval functions, effectively allowing an unauthorized control sphere to access information that should be protected. The vulnerability was reserved in early December 2025 and published later that month, but no CVSS score has been assigned yet, and no known exploits have been reported in the wild. The lack of authentication requirements for exploitation suggests that attackers could leverage this vulnerability remotely without prior access. The plugin is used primarily within WordPress environments to manage print workflows, and the exposure of sensitive data could facilitate further attacks such as privilege escalation, lateral movement, or targeted phishing. The vulnerability’s technical details remain limited, but the core issue revolves around improper access control and data exposure within the plugin’s embedded data retrieval mechanisms. Organizations using this plugin should consider the risk of confidential data leakage and the potential for attackers to gain insights into system configurations or credentials.

For European organizations, the exposure of sensitive system information can have significant consequences. Confidential data leakage can lead to intellectual property theft, compromise of user credentials, and increased risk of subsequent attacks such as ransomware or data breaches. Organizations relying on the Eight Day Week Print Workflow plugin in their content management or document processing pipelines may inadvertently expose internal system details to unauthorized parties. This can undermine trust, lead to regulatory non-compliance (e.g., GDPR violations if personal data is exposed), and cause operational disruptions. The impact is heightened for sectors with stringent data protection requirements such as finance, healthcare, and government. Additionally, the ease of exploitation without authentication increases the attack surface, potentially allowing widespread scanning and exploitation attempts. The absence of known exploits in the wild currently limits immediate risk, but the vulnerability’s public disclosure may prompt attackers to develop exploits. European organizations must therefore proactively address this vulnerability to avoid data exposure and associated reputational and financial damage.

1. Monitor 10up’s official channels for security patches addressing CVE-2025-67621 and apply updates promptly once available. 2. Until patches are released, restrict access to the Eight Day Week Print Workflow plugin interfaces by implementing network-level controls such as IP whitelisting or VPN-only access. 3. Review and harden access permissions within WordPress to ensure only trusted administrators can interact with the plugin’s settings and data retrieval functions. 4. Conduct thorough audits of embedded data within the plugin to identify and remove any unnecessary sensitive information. 5. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. 6. Monitor logs for unusual access patterns or data retrieval attempts related to the plugin. 7. Educate IT and security teams about the vulnerability to ensure rapid response to any exploitation attempts. 8. Consider isolating the print workflow environment from critical systems to limit lateral movement if exploitation occurs.
