CVE-2025-47465 is a Missing Authorization vulnerability (CWE-862) identified in the CreativeThemes Blocksy product, affecting versions up to 2.0.97. This vulnerability arises due to incorrectly configured access control security levels, allowing an attacker with certain privileges to perform actions or access resources without proper authorization checks. Specifically, the CVSS vector indicates that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), but requires the attacker to have high privileges (PR:H) and no user interaction (UI:N). The impact is primarily on integrity (I:H), with no direct confidentiality (C:N) or availability (A:N) impact. This suggests that an authenticated user with elevated privileges could exploit this flaw to modify or tamper with data or system configurations beyond their intended permissions. The vulnerability does not require user interaction, making it easier to exploit once the attacker has the necessary privileges. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published recently in May 2025 and has been enriched by CISA, indicating recognition by US cybersecurity authorities. The lack of a patch and the medium severity score (4.9) highlight the need for timely mitigation to prevent potential misuse.

For European organizations using the Blocksy theme, particularly those managing WordPress sites with administrative or privileged users, this vulnerability poses a risk of unauthorized modification of site content, configurations, or potentially sensitive data integrity breaches. Since the flaw requires high privileges, the threat is mainly from insider threats or compromised privileged accounts. The integrity impact could lead to defacement, unauthorized content injection, or manipulation of site behavior, which can damage brand reputation, erode customer trust, and potentially violate data protection regulations such as GDPR if manipulated data affects personal information. The absence of availability or confidentiality impact reduces the risk of direct data leaks or service outages but does not eliminate reputational and operational risks. Organizations relying on Blocksy for critical web presence or e-commerce should be particularly cautious, as integrity compromises can lead to financial loss or regulatory scrutiny. The medium severity rating suggests moderate urgency but should not be ignored given the potential for privilege escalation misuse.

1. Immediately audit all privileged accounts and reduce the number of users with high privileges to the minimum necessary. 2. Implement strict access control policies and monitor for unusual privileged user activities. 3. Until a patch is released, consider disabling or restricting features in Blocksy that require elevated privileges or limit the use of the affected versions. 4. Employ Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting Blocksy administrative endpoints. 5. Regularly update WordPress core, plugins, and themes, and subscribe to vendor security advisories for timely patch deployment once available. 6. Conduct thorough penetration testing focusing on authorization controls within Blocksy to identify any other potential weaknesses. 7. Educate administrators on secure credential management and the risks of privilege misuse. 8. Monitor logs for signs of exploitation attempts and establish incident response procedures specific to web application integrity breaches.
