CVE-2025-60448 is a stored Cross-Site Scripting (XSS) vulnerability identified in Emlog Pro version 2.5.19, specifically within the /admin/media.php component. The root cause of this vulnerability is insufficient validation of SVG file uploads. SVG files are XML-based vector images that can contain embedded JavaScript code. Due to inadequate sanitization or validation of the SVG content during upload, an attacker can craft a malicious SVG file embedding JavaScript payloads. When an administrator or user with access views the uploaded SVG file through the media management interface, the embedded JavaScript executes in the context of the victim's browser session. This stored XSS attack can lead to session hijacking, privilege escalation, defacement, or further exploitation of the administrative interface. The vulnerability does not require user interaction beyond viewing the malicious file and does not require authentication to upload if the attacker has access to the upload functionality, which is typically restricted to authenticated users. No CVSS score has been assigned yet, and no known public exploits have been reported. However, the presence of stored XSS in an administrative component poses a significant risk due to the potential for persistent malicious code execution within a trusted environment.

For European organizations using Emlog Pro 2.5.19, this vulnerability could have serious consequences. Stored XSS in an administrative interface can lead to compromise of administrator accounts, enabling attackers to gain elevated privileges, manipulate website content, or deploy further malware. This can result in data breaches, defacement, loss of customer trust, and regulatory non-compliance under GDPR due to unauthorized access or data leakage. The attack vector through SVG uploads is particularly concerning because SVG files are commonly used for scalable graphics, and administrators may not suspect them as a threat vector. Organizations relying on Emlog Pro for content management or blogging platforms may face operational disruptions and reputational damage if exploited. Additionally, the lack of a patch or mitigation at the time of disclosure increases the window of exposure. European entities with public-facing websites or intranet portals using this software are at risk of targeted attacks, especially if attackers can gain upload privileges or exploit weak authentication controls.

To mitigate this vulnerability, European organizations should immediately restrict access to the /admin/media.php upload functionality to only trusted administrators and enforce strong authentication mechanisms such as multi-factor authentication. Implement strict input validation and sanitization for SVG uploads, ideally disallowing SVG files unless absolutely necessary. If SVG uploads are required, use server-side libraries that safely parse and sanitize SVG content to remove any embedded scripts or potentially malicious elements before storage or rendering. Monitor and audit upload logs for suspicious activity. Additionally, isolate the media management interface from other critical systems and consider deploying Content Security Policy (CSP) headers to limit the impact of any injected scripts. Organizations should also stay alert for official patches or updates from Emlog Pro and apply them promptly once available. In the interim, consider disabling SVG uploads entirely or replacing the media management component with a more secure alternative. Regular security training for administrators about the risks of file uploads and XSS attacks is also recommended.
