CVE-2026-4511Public exploitNetwork attack vector

Authenticated code execution via LLM-generated Plotly code

Published Mar 21, 2026 · Updated Mar 21, 2026

Code injection in Vanna 2.0.0 through 2.0.2 allows remote authenticated users to execute commands through crafted chat prompts. The legacy visualization path asks the LLM for Plotly Python code and passes its output to exec() in the host process without constraining injected statements. The path requires visualization to be enabled and prompt-submission access; successful injection runs with the server process's privileges.
