CVE-2026-54528 jupyterlab-git excluded_paths Case-Sensitivity Bypass Allows Reading Excluded Directories

JupyterLab Git is a Git extension for JupyterLab. Prior to 0.54.0, jupyterlab-git uses fnmatch.fnmatchcase in GitHandler.prepare in jupyterlabgit/handlers.py to enforce excludedpaths, allowing an authenticated user on a case-insensitive filesystem to vary URL path casing and read excluded...
