CVE-2026-0571 identifies a path traversal vulnerability in the yeqifu warehouse software, specifically within the createResponseEntity function located in AppFileUtils.java. The vulnerability arises from improper validation or sanitization of the 'path' parameter, which attackers can manipulate to traverse directories and access files outside the intended directory scope. This can lead to unauthorized disclosure of sensitive files on the server hosting the application. The vulnerability is remotely exploitable without user interaction and requires only low privileges, making it relatively easy to exploit. The product follows a rolling release model, complicating version tracking and patch management. The CVSS 4.0 score of 5.3 reflects a medium severity, primarily due to the confidentiality impact and ease of exploitation, but limited impact on integrity and availability. No known exploits are currently active in the wild, but a public exploit has been released, increasing the likelihood of exploitation attempts. The vulnerability does not require authentication, increasing exposure. The flaw can be leveraged by attackers to gain access to configuration files, credentials, or other sensitive data stored on the server, potentially facilitating further attacks or data breaches. The lack of patch links suggests that users must rely on vendor updates or implement mitigations themselves. Overall, this vulnerability represents a significant risk to confidentiality and requires prompt attention.

For European organizations, the primary impact is unauthorized disclosure of sensitive information due to path traversal exploitation. This can lead to exposure of confidential business data, customer information, or internal configuration files, potentially resulting in data breaches and compliance violations under regulations like GDPR. The vulnerability could also serve as a foothold for attackers to escalate privileges or move laterally within networks. Sectors such as logistics, warehousing, and supply chain management that rely on yeqifu warehouse software are particularly at risk. The medium severity indicates that while the vulnerability is not immediately catastrophic, it poses a meaningful risk that could disrupt operations or damage reputation if exploited. The remote exploitability without user interaction increases the threat surface, especially for internet-facing deployments. European organizations with limited patch management capabilities or those unaware of the rolling release model may face delays in remediation, increasing exposure time. Additionally, the public availability of an exploit raises the likelihood of opportunistic attacks targeting vulnerable systems in Europe.

1. Implement strict input validation and sanitization on all user-supplied path parameters to prevent directory traversal sequences such as '../'. 2. Employ allowlisting for file paths or filenames to restrict access strictly to intended directories and files. 3. Use secure coding practices to avoid constructing file paths directly from user input without canonicalization. 4. Deploy runtime application self-protection (RASP) or web application firewalls (WAF) configured to detect and block path traversal patterns. 5. Monitor logs and alerts for suspicious access attempts involving unusual file paths or directory traversal indicators. 6. Engage with the vendor to obtain patches or updates aligned with the rolling release cycle and apply them promptly. 7. Isolate the application environment with least privilege file system permissions to limit the impact of potential exploitation. 8. Conduct regular security assessments and penetration testing focusing on file access controls. 9. Educate development and operations teams about the risks of path traversal and secure coding standards. 10. Consider network segmentation to reduce exposure of critical systems running yeqifu warehouse software.
