PYSEC-2026-2539 jupyterlab-git excluded_paths Case-Sensitivity Bypass Allows Reading Excluded Directories

Summary jupyterlab-git 0.53.0 latest, 2026-04-30 uses fnmatch.fnmatchcase in GitHandler.prepare jupyterlabgit/handlers.py:91 to enforce the admin-configured excludedpaths security control. Because fnmatchcase is unconditionally case-sensitive, an authenticated user on a case-insensitive filesyste...

Dulwich has unbounded memory allocation in receive-pack from crafted thin packs

ImpactAn uncontrolled-resource-consumption memory exhaustion denial-of-service vulnerability CWE-400 / CWE-789.A client with push access could push a tiny crafted thin pack 174 bytes whose delta header declares a huge destsize. When dulwich ingested it via addthinpack / applydelta, it would...

PYSEC-2026-2463 Dulwich has an arbitrary file write via NTFS-hostile tree entries on Windows

Impact Arbitrary file write leading to remote code execution when cloning or checking out a malicious Git repository on Windows. Dulwich's path-element validator accepted tree entries whose filenames contained bytes that Windows interprets as structural path syntax: - \ — the Windows path...

PYSEC-2026-2957 Prefect has an Argument Injection issue

A vulnerability in the GitHubRepository block of the prefect-github integration in Prefect version 3.6.18 allows an attacker to inject arbitrary git command-line options via the reference field. The reference field is concatenated directly into a git clone command string without proper...

GuardDog has a blind GitHub URL rewrite in remote project scanning causes SSRF and `GH_TOKEN` exfiltration

SummaryThe programmatic remote project scanning path rewrites attacker-controlled repository URLs using a blind string replacement and then sends the caller's GitHub credentials with the resulting request. This allows an attacker who can influence the scanned repository URL to trigger SSRF and...

pyp2spec is Vulnerable to Code Injection

Impactpyp2spec was writing PyPI package metadata e.g. the summary field into the generated spec file without escaping RPM macro directives. When a packager then runs rpmbuild, those directives get evaluated, so a malicious package can execute arbitrary commands on the build machine.The macro...

CVE-2026-58065

The CVE affects the Apache Airflow Git provider when performing git-over-SSH operations with StrictHostKeyChecking=no, which disables SSH host-key verification and enables MITM risk between an Airflow worker and the Git server. Deployments that clone over SSH using a deploy key or involve the Git...

CVE-2026-58065 Apache Airflow Git provider: Git provider hook defaults to StrictHostKeyChecking=no, disabling SSH host-key verification

The Apache Airflow Git provider runs its git-over-SSH operations with StrictHostKeyChecking=no by default, disabling SSH host-key verification. An attacker who can intercept the network path between an Airflow worker and the Git server can impersonate the server man-in-the-middle, capturing the S...
