CVE-2024-1602Public exploitNetwork attack vector

Remote code execution via stored model-output XSS

Published Apr 10, 2024 · Updated Aug 1, 2024

Stored XSS in ParisNeo LoLLMs WebUI allows remote attackers to execute server-side code through malicious model output. Unsanitized model output is stored and rendered as active JavaScript in the browser, which can call the unprotected /execute_code endpoint. A user must view the poisoned output; the script then executes code and can open a reverse shell with the service's privileges.
