CyberRota Analysis

AI-Generated

The vulnerability affects the unstructured library, which processes various document types, allowing an attacker to exploit the url argument in specific functions without proper host validation. This can lead to unauthorized access to internal services, potential data leakage, and server-side request forgery (SSRF) attacks. Organizations using affected versions (0.4.7 to 0.24.0) should prioritize upgrading to version 0.24.0 to mitigate these critical risks.

Original NVD Description

The unstructured library provides open-source components for ingesting and pre-processing images and text documents, such as PDFs, HTML, Word docs, and many more. From 0.4.7 until 0.24.0, the url argument of partition, partition_html, and partition_md is fetched without host validation in unstructured/partition/auto.py, unstructured/partition/html/partition.py, and unstructured/partition/md.py. An attacker who controls that URL can make a server-side ingestion service request loopback addresses, internal HTTP services, or cloud metadata endpoints through direct targets, redirects, or DNS rebinding. The response body is returned as Element text, allowing internal response disclosure, and side-effecting GET endpoints may also be triggered. This issue is fixed in version 0.24.0.
