CVE-2026-0571 is a path traversal vulnerability identified in the yeqifu warehouse product, specifically in the createResponseEntity function located in the AppFileUtils.java source file. The vulnerability arises from improper validation or sanitization of the 'path' argument, which an attacker can manipulate to traverse directories and access files outside the intended directory scope. This flaw allows remote attackers to read arbitrary files on the server without requiring authentication or user interaction. The vulnerability has been assigned a CVSS 4.0 score of 5.3, indicating medium severity, with an attack vector of network (remote), low attack complexity, no privileges required, and no user interaction needed. The product follows a rolling release model, complicating version-specific patching since no fixed versions are identified. Although no known exploits are currently active in the wild, a public exploit has been released, increasing the risk of exploitation. The impact primarily concerns confidentiality, as unauthorized file access could expose sensitive data, configuration files, or credentials. The vulnerability does not directly affect integrity or availability but could be leveraged as part of a broader attack chain. Given the continuous delivery model, organizations must monitor updates closely and apply fixes promptly once available.

For European organizations, this vulnerability poses a significant risk of unauthorized disclosure of sensitive information stored on servers running yeqifu warehouse. Confidential files such as configuration data, credentials, or proprietary information could be exposed, leading to potential data breaches and compliance violations under regulations like GDPR. The ability to exploit this remotely without authentication increases the threat level, especially for internet-facing deployments. While the vulnerability does not directly impact system integrity or availability, attackers could use accessed files to facilitate further attacks, such as privilege escalation or lateral movement. Organizations in sectors with high data sensitivity—such as finance, healthcare, and critical infrastructure—face elevated risks. Additionally, the rolling release nature of the product means that unpatched instances may remain vulnerable for extended periods if update management is not rigorous. The public availability of an exploit increases the likelihood of opportunistic attacks, emphasizing the need for immediate mitigation.

European organizations should implement the following specific mitigation measures: 1) Immediately audit all instances of yeqifu warehouse to identify affected deployments, focusing on those exposed to external networks. 2) Engage with the vendor or community to obtain patches or updates addressing the vulnerability; given the rolling release model, subscribe to update notifications and apply fixes promptly. 3) Implement strict input validation and sanitization controls at the application layer to restrict path parameters, employing allowlists and canonicalization to prevent directory traversal. 4) Employ web application firewalls (WAFs) with custom rules to detect and block path traversal attack patterns targeting the createResponseEntity function. 5) Restrict file system permissions to limit the application's access to only necessary directories, minimizing the impact of potential traversal. 6) Monitor logs for suspicious access patterns or attempts to access sensitive files outside expected directories. 7) Isolate critical systems running yeqifu warehouse behind network segmentation and limit exposure to untrusted networks. 8) Conduct regular security assessments and penetration tests focusing on path traversal and related vulnerabilities. These targeted actions go beyond generic advice by focusing on the unique aspects of this vulnerability and the product's deployment model.
