CVE-2025-49992 identifies a reflected Cross-site Scripting (XSS) vulnerability in the ThimPress LearnPress Export Import WordPress plugin, specifically affecting versions up to 4.0.9. The vulnerability arises from improper neutralization of input during web page generation, allowing attackers to inject malicious scripts into web pages viewed by other users. Because the vulnerability is reflected, it typically requires an attacker to craft a malicious URL or input that, when visited or submitted by a user, causes the injected script to execute in the victim's browser context. This can lead to theft of sensitive information such as cookies or session tokens, unauthorized actions on behalf of the user, or redirection to malicious sites. The CVSS 3.1 base score of 7.1 reflects a high severity level, with an attack vector over the network, low attack complexity, no privileges required, but requiring user interaction. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component, and impacts confidentiality, integrity, and availability to a limited extent. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and thus may be targeted by attackers. The plugin is widely used in educational environments for managing course export and import functions, making it a valuable target for attackers seeking to compromise e-learning platforms. The vulnerability was reserved in June 2025 and published in October 2025, indicating recent discovery and disclosure. No official patches are linked yet, so users must monitor vendor updates closely. The technical root cause is insufficient input sanitization and output encoding during dynamic web page generation, a common vector for reflected XSS attacks.

For European organizations, especially educational institutions and e-learning providers using the LearnPress Export Import plugin, this vulnerability poses significant risks. Successful exploitation can lead to unauthorized disclosure of user credentials, session hijacking, and potential lateral movement within networks. Confidentiality is at risk due to possible theft of sensitive user data. Integrity can be compromised if attackers perform unauthorized actions on behalf of users. Availability impact is generally limited but could occur if attackers use the vulnerability to inject disruptive scripts. Given the plugin's role in managing course data, exploitation could disrupt educational services and damage organizational reputation. The requirement for user interaction means phishing or social engineering campaigns could be used to lure users into triggering the exploit. The vulnerability's network accessibility and lack of required privileges increase the attack surface, making it easier for external attackers to target European organizations. Additionally, the scope change indicates that the impact could extend beyond the plugin itself, potentially affecting other components or user sessions.

Organizations should immediately inventory their WordPress installations to identify the presence of the LearnPress Export Import plugin and verify the version in use. Until an official patch is released by ThimPress, administrators should consider disabling the plugin or restricting access to its functionalities to trusted users only. Implementing Web Application Firewall (WAF) rules to detect and block reflected XSS payloads targeting the plugin's endpoints can provide temporary protection. Enforce strict Content Security Policy (CSP) headers to limit script execution sources and reduce the impact of injected scripts. Educate users about the risks of clicking on suspicious links, as user interaction is required for exploitation. Review and enhance input validation and output encoding practices within the plugin if custom modifications exist. Monitor web server and application logs for unusual requests or error patterns indicative of attempted exploitation. Once patches are available, prioritize timely updates and test them in staging environments before deployment. Consider deploying security plugins that provide XSS protection and regularly scan for vulnerabilities.
