CVE-2025-8912 is a high-severity vulnerability classified under CWE-36 (Absolute Path Traversal) affecting the WellChoose Organization Portal System. This vulnerability allows unauthenticated remote attackers to exploit an absolute path traversal flaw to read arbitrary files on the affected system. The flaw arises because the application does not properly sanitize user-supplied input used in file path operations, enabling attackers to specify absolute paths and access sensitive files outside the intended directory scope. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network, increasing its risk profile. The CVSS v3.1 base score of 7.5 reflects the high confidentiality impact due to unauthorized disclosure of potentially sensitive system files, while integrity and availability remain unaffected. No known exploits in the wild have been reported yet, and no patches have been published at the time of disclosure. The affected product version is listed as "0," which likely indicates an initial or early release version of the WellChoose Organization Portal System. This portal system is presumably used by organizations to manage internal or external operations, making the exposure of system files potentially damaging to organizational security and privacy.

For European organizations using the WellChoose Organization Portal System, this vulnerability poses a significant risk of unauthorized disclosure of sensitive information such as configuration files, credentials, or internal documentation. Such data leakage could facilitate further attacks, including lateral movement, privilege escalation, or targeted espionage. The lack of authentication requirement means attackers can exploit this vulnerability without prior access, increasing the attack surface. Confidentiality breaches could lead to regulatory non-compliance under GDPR, resulting in legal and financial penalties. Additionally, exposure of internal system files might undermine trust with customers and partners. Although integrity and availability are not directly impacted, the confidentiality breach alone can have severe operational and reputational consequences.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include restricting external access to the Organization Portal System via network segmentation and firewall rules, ensuring that only trusted internal IP ranges can reach the portal. Web application firewalls (WAFs) should be configured to detect and block path traversal patterns in HTTP requests. Organizations should conduct thorough input validation and sanitization on all file path parameters to prevent traversal sequences such as '../'. Monitoring and logging access to sensitive files and unusual portal activity can help detect exploitation attempts early. If possible, disable or restrict file read functionalities until a vendor patch is available. Organizations should engage with WellChoose for timely patch releases and apply updates promptly once available. Regular security assessments and penetration tests focusing on file path handling should be conducted to verify the effectiveness of mitigations.
