CVE-2025-48153 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability affecting the Atakan Au Import CDN-Remote Images plugin, versions up to 2.1.2. The vulnerability allows an attacker to perform unauthorized actions on behalf of an authenticated user by exploiting the lack of proper CSRF protections. Specifically, this vulnerability can lead to Stored Cross-Site Scripting (XSS), where malicious scripts are permanently injected into the application via the plugin's functionality that imports remote images through a CDN. The CVSS 3.1 base score of 7.1 reflects the network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality, integrity, and availability at a low level, but the stored XSS component can be leveraged for more severe attacks such as session hijacking, credential theft, or further exploitation of the affected web application. No known exploits are currently in the wild, and no patches have been published yet. The vulnerability is categorized under CWE-352, which is a common web security weakness related to CSRF attacks.

For European organizations, this vulnerability poses a significant risk especially for those using the Atakan Au Import CDN-Remote Images plugin in their web infrastructure. The stored XSS resulting from the CSRF attack can lead to compromise of user sessions, unauthorized actions, and potential data leakage. Organizations handling sensitive personal data under GDPR could face compliance violations if attackers exploit this vulnerability to access or manipulate personal data. The attack requires user interaction but no authentication, meaning that even unauthenticated attackers can trick users into executing malicious requests. This can impact web services, content management systems, or any web-facing applications using the vulnerable plugin, potentially leading to reputational damage, financial loss, and regulatory penalties. The lack of a patch increases exposure time, emphasizing the need for immediate mitigation. The scope change indicates that the vulnerability could affect multiple components or users beyond the initial target, increasing the potential impact on organizational operations.

1. Immediately audit all web applications and services using the Atakan Au Import CDN-Remote Images plugin to identify affected versions (up to 2.1.2). 2. Until an official patch is released, implement web application firewall (WAF) rules to detect and block CSRF attack patterns and suspicious requests targeting the plugin's endpoints. 3. Employ strict Content Security Policy (CSP) headers to limit the impact of stored XSS by restricting script execution sources. 4. Enforce anti-CSRF tokens in all state-changing requests within the application to prevent unauthorized actions. 5. Educate users about phishing and social engineering tactics that could be used to exploit this vulnerability. 6. Monitor logs for unusual activities or repeated failed requests that may indicate exploitation attempts. 7. Plan for rapid deployment of patches once available and consider temporary disabling or replacing the vulnerable plugin if feasible. 8. Conduct penetration testing focused on CSRF and XSS vectors to validate the effectiveness of mitigations.
