Versions of the package @tootallnate/once before 3.0.1 are vulnerable to Incorrect Control Flow Scoping in promise resolving when AbortSignal option is used. The Promise remains in a permanently pending state after the signal is aborted, causing any await or .then() usage to hang indefinitely. This can cause a control-flow leak that can lead to stalled requests, blocked workers, or degraded application availability.

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-301cbbe347 advisory.

    This update contains upgrades to various npm packages used during the build to address CVEs, namely:

    - CVE-2025-69873 (ajv)
    - CVE-2026-0540 (DOMPurify)
    - CVE-2026-3449 (@tootallnate/once)
    - CVE-2026-4800 (lodash)
    - CVE-2026-6321 (fast-uri)
    - CVE-2026-41240 (DOMPurify)

    This is probably unimportant since these packages are used at build-time only.  They are not shipped with     python3-jupytext and therefore do not affect runtime.


Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
