CVE-2025-13266 is a security vulnerability identified in the wwwlike vlife software, versions 2.0.0 and 2.0.1. The vulnerability exists in the create function within the SysFileApi.java file, part of the VLifeApi component. Specifically, the issue arises from improper sanitization of the fileName parameter, which allows an attacker to perform a path traversal attack. By manipulating this argument, an attacker can traverse directories and access files outside the intended directory scope, potentially exposing sensitive files or system data. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impact on confidentiality (VC:L) but no impact on integrity or availability. Although no active exploitation has been reported, the public disclosure of the exploit code increases the likelihood of future attacks. The vulnerability affects the wwwlike vlife product, which is used in various enterprise environments for content management and file handling. Without proper mitigation, attackers could leverage this flaw to access sensitive configuration files, credentials, or other critical data stored on the server, potentially leading to further compromise or data leakage.

For European organizations, this vulnerability poses a significant risk of unauthorized data access and potential information disclosure. Organizations using wwwlike vlife 2.0.0 or 2.0.1 in sectors such as government, finance, healthcare, or critical infrastructure could face exposure of sensitive files, leading to compliance violations under GDPR and other data protection regulations. The ability to remotely exploit this vulnerability without authentication increases the threat surface, making it attractive for cybercriminals and state-sponsored actors. If exploited, attackers could gain insights into internal system configurations or harvest credentials, facilitating lateral movement or further attacks. The medium severity rating reflects the partial confidentiality impact and ease of exploitation, but the lack of integrity or availability impact limits the scope of damage. However, the strategic importance of affected systems in European organizations means even partial data exposure could have serious operational and reputational consequences.

European organizations should immediately assess their deployment of wwwlike vlife and identify instances running versions 2.0.0 or 2.0.1. Since no official patches are currently linked, organizations should implement strict input validation and sanitization on the fileName parameter to prevent path traversal sequences such as '../'. Employing allowlists for acceptable file paths and names can reduce risk. Restricting the file system permissions of the application to limit access only to necessary directories will minimize potential damage. Network-level controls such as web application firewalls (WAFs) can be configured to detect and block path traversal attack patterns. Continuous monitoring and logging of file access attempts should be enhanced to detect suspicious activity early. Organizations should also prepare to apply vendor patches promptly once available and consider isolating affected systems until mitigations are in place. Conducting security audits and penetration testing focused on path traversal vulnerabilities will help identify residual risks.
