    Disclosure

    Interesting GitHub Security Lab disclosure: same-second TOCTOU in jupyterlab/maintainer-tools update-snapshots-checkout (CVE-2026-84973). Race between checkout and snapshot update. Window is measured in the same second the workflow runs. Classic TOCTOU, but in a maintainer tooling path that many projects inherit. https://securitylab.github.com/advisories/GHSL-2026-203_jupyter_notebook_repository/ #AppSec #SupplyChain

    Post summary

    GitHub Security Lab disclosed a same‑second TOCTOU race in jupyterlab maintainer‑tools, but no exploit, patch, or active exploitation is mentioned.

    Patch

    A maintainer approved one commit. A same second push let a different commit inherit that approval in CVE-2026-84973. GitHub Security Lab verified the race before JupyterLab fixed the action in v1.0.0. Bind approval to the SHA not the clock. https://sunglasses.dev/blog/ai-agent-workflow-security-needs-proof #AgenticAISecurity #AISecurity #cybersecuritytips #Sunglassesdev

    Post summary

    The post discloses CVE-2026-84973 as a race condition in GitHub commit approvals, verified by GitHub Security Lab, and indicates that JupyterLab’s v1.0.0 release fixes the issue.
