CVE-2025-8815 is a path traversal vulnerability identified in the 猫宁i Morning product, specifically within an unknown function in the /index file of the Shiro Configuration component. This vulnerability allows an unauthenticated attacker to remotely manipulate input parameters to traverse directories outside the intended file system scope. Path traversal vulnerabilities typically enable attackers to access sensitive files and directories on the server, potentially exposing configuration files, credentials, or other critical data. The product uses a rolling release model, which means continuous delivery without fixed version numbers, complicating precise identification of affected or patched versions. The vulnerability has been publicly disclosed, but no known exploits are currently observed in the wild. The CVSS 4.0 base score is 6.9 (medium severity), reflecting network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. The vulnerability does not require authentication or user interaction, increasing its risk profile. However, the impact is limited to partial compromise of confidentiality, integrity, and availability, and there is no indication of privilege escalation or remote code execution. The lack of patch information and the rolling release nature of the product complicate mitigation efforts, requiring organizations to monitor updates closely and implement compensating controls.

For European organizations using 猫宁i Morning, this vulnerability poses a risk of unauthorized access to sensitive files and data, potentially leading to information disclosure or manipulation of configuration files. This can undermine the confidentiality and integrity of organizational data and may disrupt service availability if critical files are accessed or modified. Given the remote and unauthenticated nature of the exploit, attackers could leverage this vulnerability to gain footholds in affected systems, potentially facilitating further attacks or lateral movement within networks. The impact is particularly concerning for sectors handling sensitive personal data or critical infrastructure, where data breaches or service disruptions could have regulatory and operational consequences. However, the medium severity rating and absence of known active exploits suggest the immediate risk is moderate but warrants proactive attention.

1. Immediate mitigation should include implementing strict input validation and sanitization on all user-supplied parameters, especially those interacting with file system paths, to prevent directory traversal sequences such as '../'. 2. Employ web application firewalls (WAFs) configured to detect and block path traversal attempts targeting the /index endpoint or Shiro Configuration components. 3. Restrict file system permissions for the application process to the minimum necessary, preventing access to sensitive directories and files outside the application scope. 4. Monitor logs for unusual access patterns or attempts to access unauthorized files, enabling early detection of exploitation attempts. 5. Engage with the vendor or community to obtain timely updates or patches, given the rolling release model, and apply them promptly once available. 6. Consider network segmentation and isolation of systems running 猫宁i Morning to limit exposure. 7. Conduct regular security assessments and penetration testing focusing on path traversal and related vulnerabilities to identify and remediate weaknesses proactively.
