CVE-2025-47445 is a high-severity Relative Path Traversal vulnerability (CWE-23) affecting the Themewinter Eventin product up to version 4.0.26. This vulnerability allows an unauthenticated remote attacker to manipulate file paths by exploiting insufficient validation of user-supplied input, enabling traversal outside the intended directory structure. Specifically, the attacker can craft requests that include relative path sequences (e.g., '../') to access arbitrary files on the server's filesystem. The CVSS 3.1 base score of 7.5 reflects the vulnerability's characteristics: it is remotely exploitable over the network (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), with a low attack complexity (AC:L). The impact is primarily on confidentiality (C:H), as attackers can read sensitive files, but there is no direct impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that mitigation may require vendor updates or manual intervention. The vulnerability is significant because Eventin is a WordPress event management plugin used to create and manage event-related content, and unauthorized file access could expose configuration files, credentials, or other sensitive data stored on the web server, potentially leading to further compromise.

For European organizations using the Themewinter Eventin plugin, this vulnerability poses a substantial risk to the confidentiality of sensitive information. Attackers could access configuration files containing database credentials, API keys, or other sensitive data, which may lead to data breaches or lateral movement within the network. Organizations handling personal data under GDPR are particularly at risk, as unauthorized disclosure could result in regulatory penalties and reputational damage. Since the vulnerability does not require authentication or user interaction, it can be exploited by remote attackers scanning for vulnerable installations, increasing the likelihood of widespread exploitation. The impact is especially critical for event management platforms used by businesses, educational institutions, or public sector entities in Europe, where exposure of internal documents or personal data could have severe operational and compliance consequences.

European organizations should immediately audit their WordPress installations to identify the presence and version of the Themewinter Eventin plugin. Until an official patch is released, organizations should consider the following mitigations: 1) Restrict direct access to sensitive directories via web server configuration (e.g., using .htaccess rules or equivalent) to prevent unauthorized file reads. 2) Implement Web Application Firewall (WAF) rules to detect and block requests containing path traversal patterns such as '../'. 3) Limit the plugin's file system permissions to the minimum necessary, preventing it from reading files outside its designated directories. 4) Monitor web server logs for suspicious requests indicative of path traversal attempts. 5) If possible, temporarily disable or replace the Eventin plugin with alternative solutions until a secure version is available. 6) Stay informed through vendor communications and apply patches promptly once released. These steps go beyond generic advice by focusing on immediate containment and detection strategies tailored to this specific vulnerability.
