CVE-2021-32797

Advisory

Jupyterlab versions 3.1.4, 3.0.17, 2.3.2, 2.2.10 and 1.2.21 include a fix for CVE-2021-32797: In affected versions, an untrusted notebook can execute code on load. In particular, jupyterlab doesn’t sanitize the action attribute of html "<form>". Using this it is possible to trigger the form validation outside of the form itself. This is a remote code execution, but requires user action to open a notebook.
