CVE-2026-54528 High · 7.1 CWE-178 Jul 8, 2026

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 jupyterlab_git/handlers.py to enforce excluded_paths, allowing an authenticated user on a case-insensitive filesystem to vary URL path casing and read excluded directories. This issue is fixed in version 0.54.0.

CVE-2026-54527 Critical · 9.0 CWE-79 Jul 8, 2026

JupyterLab Git: Stored XSS leading to RCE

JupyterLab Git is a Git extension for JupyterLab. From 0.30.0b3 before 0.54.0, the PlainTextDiff.ts createHeader() method passes Git filenames directly to innerHTML when rendering renamed files in commit history, allowing a crafted filename to execute JavaScript when a victim views the rename diff in the Git History tab. This issue is fixed in version 0.54.0.
