Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-115: Misinterpretation of Input, where the product misinterprets an input, whether from an attacker or another product, in a security-relevant fashion. In Github.com/mudler/LocalAI, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

mudler/localai version v2.21.1 contains a Cross-Site Scripting (XSS) vulnerability in its search functionality. The vulnerability arises due to improper sanitization of user input, allowing the injection and execution of arbitrary JavaScript code. This can lead to the execution of malicious scripts in the context of the victim's browser, potentially compromising user sessions, stealing session cookies, redirecting users to malicious websites, or manipulating the DOM.
