CVE-2025-49992 is a reflected Cross-site Scripting (XSS) vulnerability identified in the ThimPress LearnPress Export Import plugin, a WordPress plugin used to manage the import and export of e-learning content. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code that is reflected back to the user's browser. This reflected XSS does not require prior authentication, making it accessible to unauthenticated attackers who can craft malicious URLs or payloads that, when visited by a victim, execute arbitrary scripts in the victim's browser context. The impact of such an attack includes theft of session cookies, enabling account takeover, defacement, or execution of unauthorized actions on behalf of the user. The vulnerability affects all versions of LearnPress Export Import up to and including 4.0.9. Although no public exploits have been reported yet, the nature of reflected XSS vulnerabilities makes them relatively straightforward to exploit, especially in phishing or social engineering scenarios. The vulnerability was reserved in June 2025 and published in October 2025, but no CVSS score or patches have been released at the time of this report. The plugin is widely used in educational and training environments, which increases the risk profile for organizations relying on it for content management. The lack of proper input validation and output encoding is the root cause, and mitigation requires both patching and additional security controls such as Content Security Policy (CSP) enforcement and user awareness to avoid clicking suspicious links.

For European organizations, especially educational institutions, e-learning providers, and training companies using WordPress with the LearnPress Export Import plugin, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information such as login credentials, and potential compromise of user accounts. This could disrupt learning services, damage organizational reputation, and lead to data breaches involving personal information of students and staff. The reflected XSS nature means attackers can leverage social engineering to trick users into clicking malicious links, increasing the attack surface. Additionally, compromised accounts could be used to escalate attacks within the organization or deliver further malware. Given the increasing reliance on digital learning platforms in Europe, the impact could be widespread if not addressed promptly.

1. Monitor ThimPress official channels and apply security patches for LearnPress Export Import as soon as they are released. 2. Implement strict input validation and output encoding on all user-supplied data within the plugin or at the web application firewall (WAF) level to prevent injection of malicious scripts. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4. Educate users and administrators about the risks of clicking on suspicious links, especially those related to e-learning platforms. 5. Use security plugins or WAF solutions that can detect and block reflected XSS attempts targeting WordPress sites. 6. Regularly audit and monitor logs for unusual activities that may indicate exploitation attempts. 7. Consider isolating or sandboxing the LearnPress Export Import functionality to limit potential damage in case of exploitation.
