GitLab RCE PoC: Any Project Pusher Can Run Commands as Git via Notebook Diff Rendering
Researchers at depthfirst published working exploit code for an unfiled GitLab RCE: a two-bug chain in the Oj JSON parser behind Jupyter notebook diff rendering lets any user who can push to a project run commands as git on unpatched self-managed instances.
Certighost (CVE-2026-54121): A Low-Privileged AD User Can Impersonate Your Domain Controller
A working exploit for CVE-2026-54121 lets any domain user request a certificate for a Domain Controller through an AD CS enrollment fallback, then use it to DCSync the krbtgt hash. No admin rights, no user interaction.
RefluXFS (CVE-2026-64600): A Nine-Year-Old XFS Race Condition Roots 16.4 Million Linux Systems
A race condition in the XFS copy-on-write path lets any local user overwrite protected files and gain root — no SELinux bypass needed, no workaround available. Patch and reboot is the only fix.
