CVE-2025-46470 is a Missing Authorization vulnerability (CWE-862) identified in the Smart Hashtags [#hashtagger] plugin developed by Peter Raschendorfer. This vulnerability arises from incorrectly configured access control security levels, allowing unauthorized users to perform actions or access resources that should be restricted. The affected versions include all versions up to 7.2.3, with no specific lower bound version identified. The vulnerability does not require prior authentication or user interaction, which increases its risk profile. Although no known exploits are currently reported in the wild, the nature of missing authorization flaws typically allows attackers to bypass security controls, potentially leading to unauthorized data access, modification, or functionality abuse within the affected system. The plugin is commonly used to manage hashtags in content management systems or social media platforms, which may involve user-generated content and metadata tagging. The lack of proper authorization checks could allow attackers to manipulate hashtag data, interfere with content categorization, or escalate privileges within the application environment. Given the plugin's integration with content platforms, exploitation could impact data integrity and confidentiality, and potentially availability if the unauthorized actions disrupt normal operations. The vulnerability was published on April 24, 2025, and has been enriched with CISA data, indicating recognition by cybersecurity authorities but no immediate active exploitation.

For European organizations, the impact of CVE-2025-46470 can be significant, especially for those relying on the Smart Hashtags [#hashtagger] plugin within their content management or social media management systems. Unauthorized access could lead to manipulation of content metadata, affecting data integrity and potentially misleading content categorization or search functionalities. This could degrade user experience, damage brand reputation, and in regulated sectors, lead to compliance violations if sensitive information is exposed or altered. Additionally, attackers might leverage this vulnerability to escalate privileges or pivot to other parts of the network, increasing the risk of broader compromise. Organizations in media, marketing, e-commerce, and public sector entities that use this plugin are particularly at risk. The absence of authentication requirements for exploitation means that attackers can attempt to exploit this vulnerability remotely and anonymously, increasing the attack surface. While availability impact is less direct, unauthorized modifications could disrupt normal content workflows or automated processes dependent on hashtag data, causing operational disruptions.

To mitigate CVE-2025-46470, European organizations should first identify all instances of the Smart Hashtags [#hashtagger] plugin in their environments and assess their version. Since no official patch links are currently available, organizations should implement compensating controls immediately: 1) Restrict access to the plugin’s management interfaces to trusted administrators via network segmentation and firewall rules. 2) Implement strict role-based access controls (RBAC) at the application level to ensure only authorized users can perform sensitive actions related to hashtag management. 3) Monitor logs for unusual or unauthorized access attempts to the plugin’s functionality. 4) If possible, disable or remove the plugin temporarily until a vendor patch is released. 5) Engage with the vendor or community to obtain updates or patches as soon as they become available. 6) Conduct security testing focused on access control enforcement around the plugin to identify and remediate any additional weaknesses. 7) Educate administrators and developers about the risks of missing authorization and the importance of secure access control configurations.
