CVE-2025-47534 is a Missing Authorization vulnerability (CWE-862) identified in the ValvePress Wordpress Auto Spinner plugin, affecting versions up to 3.25.0. This vulnerability arises due to improperly configured access control mechanisms within the plugin, allowing users with limited privileges (requiring at least some level of authentication) to perform actions or access functionality that should be restricted. Specifically, the vulnerability does not require user interaction but does require the attacker to have some level of privileges (PR:L) on the Wordpress installation. The vulnerability has a CVSS 3.1 base score of 4.3 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), no impact on confidentiality (C:N), limited impact on integrity (I:L), and no impact on availability (A:N). This means an attacker with some authenticated access can exploit the missing authorization to perform unauthorized modifications or actions that impact the integrity of the Wordpress site content or configuration, but cannot affect confidentiality or availability directly. The Wordpress Auto Spinner plugin is designed to automatically spin or rewrite content to avoid duplication, often used in SEO or content management contexts. The lack of proper authorization checks in this plugin could allow an attacker to manipulate content or settings, potentially leading to content tampering or defacement. No public exploits are known at this time, and no patches have been linked yet, indicating that mitigation may require vendor updates or manual access control reviews. The vulnerability was published on May 16, 2025, and is tracked by Patchstack and CISA enrichment, highlighting its recognition by security authorities.

For European organizations using Wordpress with the ValvePress Auto Spinner plugin, this vulnerability poses a risk primarily to the integrity of website content. Attackers with some authenticated access—such as low-privilege users, compromised accounts, or insiders—could exploit this flaw to alter or manipulate web content without proper authorization. This can lead to defacement, misinformation, or SEO manipulation, damaging brand reputation and user trust. While confidentiality and availability are not directly impacted, integrity breaches can have downstream effects such as loss of customer confidence, regulatory scrutiny under GDPR if misinformation leads to data misuse, and potential financial losses from reputational damage. Organizations relying on automated content spinning for SEO or content management are particularly at risk. Since the vulnerability requires some level of authentication, organizations with weak user access controls or poor account management are more vulnerable. The absence of known exploits reduces immediate risk, but the medium severity score and the nature of the vulnerability warrant proactive mitigation to prevent exploitation, especially given the widespread use of Wordpress in Europe.

1. Immediately audit user roles and permissions within Wordpress to ensure that only trusted users have access to plugin management and content editing capabilities. 2. Temporarily disable or uninstall the ValvePress Wordpress Auto Spinner plugin until a security patch or update is released by the vendor. 3. Monitor Wordpress logs for unusual activity from authenticated users, especially those with limited privileges performing actions beyond their role. 4. Implement multi-factor authentication (MFA) for all Wordpress user accounts to reduce the risk of compromised credentials being used to exploit this vulnerability. 5. Regularly check for updates from ValvePress and apply patches promptly once available. 6. Consider using web application firewalls (WAF) with custom rules to restrict access to plugin endpoints or suspicious requests that could exploit missing authorization. 7. Educate content managers and administrators about the risks of privilege escalation and the importance of strict access controls. 8. Review and harden Wordpress security configurations, including limiting plugin installations to trusted sources and minimizing the number of plugins in use to reduce attack surface.
