CVE-2024-4897

Code execution via unsandboxed GGUF chat templates

Published Jul 2, 2024 · Updated Aug 1, 2024

Code injection in ParisNeo LoLLMs WebUI allows attackers to execute code by loading a malicious GGUF model through bindings_zoo. The Llama constructor passes the model metadata's chat template to Jinja2ChatFormatter, which renders it with an unsandboxed Jinja2 environment. Exploitation requires loading and interacting with a crafted model; injected code runs with the LoLLMs process privileges.
