CVE-2023-35174
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedLivebook is a web application for writing interactive and collaborative code notebooks. On Windows, it is possible to open a `livebook://` link from a browser which opens Livebook Desktop and triggers arbitrary code execution on victim's machine. Any user using Livebook Desktop on Windows is potentially vulnerable to arbitrary code execution when they expect Livebook to be opened from browser. This vulnerability has been fixed in version 0.8.2 and 0.9.3.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUser input reaches a shell or system command without being fully separated from the command itself, so an attacker can append their own instructions. Because these run with the application's privileges, it often means full control of the host. The lasting fix is to avoid the shell entirely — call APIs directly and pass arguments as data, never as concatenated strings.
