CVE-2025-46530 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the HuangYe WuDeng Hacklog Remote Attachment software, affecting versions up to 1.3.2. 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 CSRF flaw enables the injection of stored Cross-Site Scripting (XSS) payloads within the application. Stored XSS occurs when malicious scripts are permanently stored on the target server (e.g., in a database or log) and executed in the context of users who access the affected content. The combination of CSRF and stored XSS significantly increases the attack surface, as an attacker can trick an authenticated user into submitting a crafted request that stores malicious scripts, which then execute in the victim’s browser during subsequent legitimate interactions. This can lead to session hijacking, credential theft, or further exploitation of the victim’s environment. The vulnerability does not require prior authentication to exploit the CSRF vector, but the victim must be authenticated for the attack to succeed. There are no known public exploits in the wild at the time of publication, and no official patches have been released yet. The vulnerability was reserved and published on April 24, 2025, with CWE-352 (CSRF) as the primary weakness classification. The affected product, Hacklog Remote Attachment, is a component used for managing remote file attachments, likely integrated into web applications or content management systems, which may be used in various organizational contexts.

For European organizations, this vulnerability poses a moderate risk primarily to web applications that incorporate the HuangYe WuDeng Hacklog Remote Attachment component. Successful exploitation could lead to unauthorized actions performed under the context of legitimate users, including the injection and execution of malicious scripts. This can compromise user confidentiality by stealing session tokens or personal data, impact integrity by altering stored data or logs, and affect availability if malicious scripts disrupt normal operations. Organizations handling sensitive or regulated data (e.g., financial institutions, healthcare providers, government agencies) could face compliance violations under GDPR if personal data is exposed or manipulated. The stored XSS aspect increases the risk of widespread impact within an organization’s user base, as malicious scripts persist and execute for multiple users. Although no active exploitation is reported, the lack of patches and the nature of CSRF combined with stored XSS make this a vulnerability that could be weaponized in targeted phishing or social engineering campaigns. The impact is heightened in environments where users have elevated privileges or where the affected component is integrated into critical workflows.

1. Implement strict anti-CSRF tokens in all forms and state-changing requests within the Hacklog Remote Attachment component to ensure requests originate from legitimate sources. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of stored XSS payloads. 3. Sanitize and validate all user inputs and outputs rigorously to prevent injection of malicious scripts into stored data. 4. Monitor and audit logs for unusual or unauthorized attachment uploads or modifications that could indicate exploitation attempts. 5. Isolate the Hacklog Remote Attachment functionality within a sandboxed environment or restrict its usage to trusted users to minimize exposure. 6. Educate users about phishing and social engineering risks that could trigger CSRF attacks. 7. Engage with the vendor or community to obtain patches or updates as soon as they become available and prioritize their deployment. 8. Where possible, implement multi-factor authentication (MFA) to reduce the risk of session hijacking resulting from XSS exploitation. 9. Conduct regular security assessments and penetration testing focused on CSRF and XSS vectors in the affected applications.
