CVE-2026-0571 is a path traversal vulnerability identified in the yeqifu warehouse software, specifically within the createResponseEntity function located in the AppFileUtils.java source file. The vulnerability arises from improper validation or sanitization of the 'path' argument, allowing an attacker to manipulate this parameter to traverse directories outside the intended file system scope. This can lead to unauthorized access to arbitrary files on the server hosting the application. The vulnerability is remotely exploitable without requiring user interaction, but it does require low-level privileges on the system, indicating that some form of authentication or access is necessary. The product operates on a rolling release basis, which complicates version tracking and patch management since no fixed version numbers are assigned to affected or fixed releases. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the moderate impact on confidentiality with no impact on integrity or availability. Although a public exploit exists, there are no confirmed reports of exploitation in the wild at this time. The vulnerability primarily threatens confidentiality by exposing sensitive files, potentially including configuration files, credentials, or other critical data stored on the server. The lack of integrity or availability impact means that the system's operation or data modification is not directly affected by this flaw. The continuous delivery model of the software necessitates vigilant monitoring for updates and patches. The vulnerability highlights the importance of secure coding practices, particularly input validation and path normalization, to prevent directory traversal attacks.

The primary impact of CVE-2026-0571 is unauthorized disclosure of sensitive information due to path traversal, which can compromise confidentiality. Attackers exploiting this vulnerability can access files outside the intended directory, potentially exposing configuration files, credentials, or other sensitive data that could facilitate further attacks or data breaches. Although the vulnerability does not affect data integrity or system availability directly, the exposure of sensitive information can lead to secondary impacts such as privilege escalation, lateral movement, or targeted attacks against the affected organization. Organizations relying on yeqifu warehouse in their supply chain or inventory management systems may face operational risks if sensitive business data is leaked. The rolling release nature of the product means that organizations must maintain continuous vigilance to detect and apply patches promptly. The medium severity score reflects the moderate risk, but the availability of a public exploit increases the urgency for mitigation. The absence of known active exploitation reduces immediate risk but does not eliminate the potential for future attacks. Overall, the vulnerability poses a significant risk to confidentiality and could undermine trust in the affected systems if exploited.

To mitigate CVE-2026-0571, organizations should implement strict input validation and sanitization on all user-supplied path parameters to ensure they do not contain directory traversal sequences such as '../'. Employ path normalization techniques to canonicalize file paths before processing to prevent bypassing security checks. Restrict file system permissions so that the application process only has access to necessary directories and files, minimizing the impact of any traversal attempts. Use application-level allowlists to limit accessible files or directories explicitly. Monitor logs for unusual file access patterns that may indicate exploitation attempts. Since the product follows a rolling release model, establish a robust update and patch management process to quickly incorporate security fixes as they become available. If possible, deploy web application firewalls (WAFs) with rules designed to detect and block path traversal payloads. Conduct regular security code reviews and penetration testing focused on input handling and file access controls. Finally, educate developers and administrators about secure coding practices and the risks associated with path traversal vulnerabilities to prevent recurrence.
