By calling org.freedesktop.Flatpak.SystemHelper.CancelPull on another user's pull, the pull is not actually cancelled but removed from internal tracking, making it impossible for the owning user to stop it. Ongoing pulls cannot be stopped.

The Rocky Linux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_1760 advisory.

    This advisory aggregates security fixes for the flatpak SRPM in CIQ LTS 9.2. It addresses 3 CVEs:
    CVE-2026-96284, CVE-2026-34079, CVE-2026-96283.

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

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

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4610-1 advisory.

    - CVE-2026-90616: missing symlink protection allows a malicious sandboxed app to obtain arbitrary read and     write access       to files on the host (bsc#1280236).
    - CVE-2026-92162: path traversal via unvalidated `arch` parameter in `DeployAppstream` (bsc#1282514).
    - CVE-2026-96275: arbitrary write access as root via extra-data extraction (bsc#1282515).
    - CVE-2026-96276: arbitrary write in host context via `flatpak build-init` (bsc#1282516).
    - CVE-2026-96281: unprivileged active user can bypass anti-downgrade checks for system apps/runtimes     (bsc#1282519).
    - CVE-2026-96282: extension metadata path traversal file existence oracle (bsc#1282520).
    - CVE-2026-96283: flatpak-system-helper: cross-user `CancelPull` orphans another user's ongoing pull     (bsc#1282521).
    - CVE-2026-96807: fixed-filename writes to arbitrary locations via symlink attack on `.ld.so`     (bsc#1282523).
    - CVE-2026-96808: `revokefs` symlink path traversal allows local privilege escalation via commit tampering       (bsc#1282524).

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - By calling org.freedesktop.Flatpak.SystemHelper.CancelPull on another user's pull, the pull is not     actually cancelled but removed from internal tracking, making it impossible for the owning user to stop     it. Ongoing pulls cannot be stopped. (CVE-2026-96283)

Note that Nessus relies on the presence of the package as reported by the vendor.
