CVE-2025-10001 is a high-severity vulnerability affecting the WordPress plugin "Import any XML, CSV or Excel File to WordPress" (wpallimport), present in all versions up to and including 3.9.3. The vulnerability is classified under CWE-434, which pertains to unrestricted file upload of dangerous file types. The core issue arises from the plugin's failure to properly validate file types during the import process. Specifically, authenticated users with Administrator-level privileges or higher can upload arbitrary files, including potentially dangerous file types such as .phar files. These files can be crafted to enable remote code execution (RCE) on the affected WordPress server. The CVSS v3.1 base score is 7.2, indicating a high severity level, with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. This means the attack can be performed remotely over the network with low attack complexity, requires high privileges (administrator), no user interaction, and impacts confidentiality, integrity, and availability significantly. Although no known exploits are currently reported in the wild, the vulnerability presents a critical risk due to the potential for full system compromise via RCE. The lack of patch links suggests that either a patch is pending or not yet publicly available at the time of reporting. The vulnerability affects all versions of the plugin, which is widely used for importing data into WordPress sites, making it a significant concern for WordPress administrators who rely on this plugin for content management and data importation.

For European organizations, this vulnerability poses a substantial risk, especially for those relying on WordPress as a content management system with the wpallimport plugin installed. Successful exploitation could lead to remote code execution, allowing attackers to execute arbitrary commands on the server, potentially leading to data breaches, website defacement, service disruption, or full server takeover. This can compromise sensitive customer data, intellectual property, and internal systems connected to the WordPress server. Given the high prevalence of WordPress in Europe across various sectors including government, education, e-commerce, and media, the impact could be widespread. Additionally, organizations subject to strict data protection regulations such as GDPR could face severe legal and financial consequences if personal data is exposed or systems are disrupted. The requirement for administrator-level access limits the attack surface but insider threats or compromised admin credentials could facilitate exploitation. The absence of known exploits in the wild currently provides a window for mitigation before active attacks emerge.

1. Immediate mitigation should involve restricting administrator access to trusted personnel only and enforcing strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. 2. Disable or remove the wpallimport plugin if it is not essential to operations until a secure patched version is released. 3. Monitor WordPress logs and server activity for any suspicious file uploads or execution attempts, particularly focusing on .phar or other unusual file types. 4. Implement web application firewall (WAF) rules to detect and block attempts to upload or execute unauthorized file types. 5. Once available, promptly apply vendor patches or updates addressing this vulnerability. 6. Conduct regular security audits and vulnerability scans on WordPress installations to identify and remediate similar issues proactively. 7. Educate administrators on the risks of file upload vulnerabilities and the importance of validating file types and sources. 8. Consider isolating WordPress environments or running them with least privilege to limit the impact of potential exploitation.
