LlamaIndex vulnerable to Path Traversal attack through its encode_image function
A path traversal vulnerability exists in run-llama/llama_index versions 0.11.23 through 0.12.40, specifically within the encode_image function in generic_utils.py. This vulnerability allows an attacker to manipulate the image_path input to read arbitrary files on the server, including sensitive system files. The issue arises due to improper validation or sanitization of the file path, enabling path traversal sequences to access files outside the intended directory. The vulnerability is fixed in version 0.12.41.
