Detailsinfo

A vulnerability was found in huggingface smolagents up to 1.21.x. It has been rated as critical. Affected by this issue is an unknown part of the file src/smolagents/vision_web_browser.py of the component XPath Expression Handler. The manipulation with an unknown input leads to a xpath injection vulnerability. Using CWE to declare the problem leads to CWE-643. The product uses external input to dynamically construct an XPath expression used to retrieve data from an XML database, but it does not neutralize or incorrectly neutralizes that input. This allows an attacker to control the structure of the query. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Hugging Face Smolagents version 1.20.0 contains an XPath injection vulnerability in the search_item_ctrl_f function located in src/smolagents/vision_web_browser.py. The function constructs an XPath query by directly concatenating user-supplied input into the XPath expression without proper sanitization or escaping. This allows an attacker to inject malicious XPath syntax that can alter the intended query logic. The vulnerability enables attackers to bypass search filters, access unintended DOM elements, and disrupt web automation workflows. This can lead to information disclosure, manipulation of AI agent interactions, and compromise the reliability of automated web tasks. The issue is fixed in version 1.22.0.
