Detailsinfo

A vulnerability was found in run-llama llama_index up to 0.12.40. It has been classified as problematic. This affects the function encode_image of the file generic_utils.py. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-29. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '\..\filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory. This is going to have an impact on confidentiality. The summary by CVE is:

A path traversal vulnerability exists in run-llama/llama_index versions 0.12.27 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.
