CVE-2025-50034 is a Missing Authorization vulnerability (CWE-862) found in the WordPress plugin "Enhanced Blocks – Page Builder Blocks for Gutenberg" developed by Mahmudul Hasan Arif. This plugin extends the Gutenberg editor by providing additional page builder blocks to enhance content creation. The vulnerability affects all versions up to and including 1.4.1. The core issue is an incorrect or missing access control mechanism, which allows users with limited privileges (requiring at least low-level privileges, as indicated by PR:L) to perform actions or access functionalities that should be restricted. The CVSS v3.1 score of 6.5 (medium severity) reflects that the vulnerability can be exploited remotely over the network (AV:N) with low attack complexity (AC:L), requiring some privileges but no user interaction (UI:N). The impact is primarily on integrity (I:H), meaning an attacker can modify or manipulate data or content within the affected system without authorization, but confidentiality and availability are not directly impacted. Since the vulnerability does not require user interaction and can be exploited by authenticated users with low privileges, it poses a risk of privilege escalation or unauthorized content manipulation within WordPress sites using this plugin. No known exploits are currently reported in the wild, and no official patches or updates have been linked yet. The vulnerability was published on June 20, 2025, shortly after being reserved on June 11, 2025, indicating recent discovery and disclosure. Overall, this vulnerability highlights a critical gap in access control implementation within the plugin, potentially allowing attackers to bypass intended permission checks and alter site content or configurations inappropriately.

For European organizations using WordPress sites with the Enhanced Blocks – Page Builder Blocks for Gutenberg plugin, this vulnerability can lead to unauthorized content modification, defacement, or insertion of malicious content, undermining the integrity of their web presence. This can damage brand reputation, erode customer trust, and potentially lead to misinformation or fraudulent activities if attackers manipulate displayed information. Organizations relying on their websites for e-commerce, communications, or public information dissemination are particularly at risk. Although the vulnerability does not directly affect confidentiality or availability, unauthorized content changes can indirectly cause operational disruptions or compliance issues, especially for sectors with strict content governance such as finance, healthcare, and government. Since exploitation requires at least some level of authenticated access, insider threats or compromised low-privilege accounts could be leveraged to exploit this flaw. The absence of known exploits in the wild suggests limited immediate risk, but the medium severity and ease of exploitation warrant proactive mitigation to prevent future attacks. Additionally, the widespread use of WordPress across European organizations means the potential attack surface is significant, especially for entities that have not updated or audited their plugins recently.

1. Immediate auditing of all WordPress sites to identify installations of the Enhanced Blocks – Page Builder Blocks for Gutenberg plugin, particularly versions up to 1.4.1. 2. Restrict plugin usage to trusted administrators only, and review user roles and permissions to minimize the number of users with authenticated access capable of exploiting this vulnerability. 3. Implement strict access control policies at the WordPress level, including role-based access control (RBAC) and the principle of least privilege for all users. 4. Monitor site content and logs for unusual modifications or unauthorized changes that could indicate exploitation attempts. 5. Until an official patch is released, consider disabling or removing the plugin if it is not essential to site functionality. 6. Engage with the plugin vendor or community to track the release of security updates and apply patches promptly once available. 7. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. 8. Educate site administrators and content managers about the risks of privilege misuse and the importance of strong authentication practices, including multi-factor authentication (MFA).
