Summary

An issue was discovered in Weaviate OSS versions prior to 1.30.20, 1.31.x prior to 1.31.19, 1.32.x prior to 1.32.16, 1.33.x prior to 1.33.4.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
