Latest Red Hat advisories
Medium [CVE-2026-100722] Denial of Service via unhandled Promise rejection in construct trap
Denial of Service via unhandled Promise rejection in construct trap. Red Hat rates this moderate (CVSS 6.8). Weakness: CWE-248. Affected products named by the advisory: Red Hat Developer Hub; Self-service automation portal 2.
Low [CVE-2026-96284] Flatpak: flatpak: arbitrary read-access to files in the system-helper context via oci symlink following
A malicious user can get read-access to files in the flatpak-system-helper context if a system OCI repository is configured, because the OCI code paths in the system helper follow symlinks when importing OCI images that are under the user's control. Red Hat estimates the CVSSv3.1 vector of CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N. Exploitation requires the attacker to be a local, authenticated user able to trigger a system-wide OCI image import via the flatpak-system-helper D-Bus service (AV:L, PR:L). This depends on the uncommon, non-default environmental precondition that a system OCI repository is configured (AC:H). No interaction from another party is required (UI:N). The vulnerable and impacted components remain within the same overall flatpak client/helper security authority (S:U). While some host file content can leak via this symlink-following behavior, disclosure surfaces only through the attacker's own crafted import under the rarer system-OCI-repository precondition, rather than through a broadly repeatable read of arbitrary files (C:L). There is no integrity or availability impact (I:N/A:N). Red Hat severity: Low — CVSS 2.5 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N). Weakness: CWE-59. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
Low [CVE-2026-96282] Flatpak: flatpak: extension metadata path traversal file existence oracle
A malicious Flatpak extension can probe the host filesystem to determine what files and directories exist at arbitrary paths, and host directory listings can be disclosed to sandboxed applications using the extension. Additionally, unvalidated extension metadata can cause extension content to be mounted at unintended locations inside the sandbox. Red Hat estimates the CVSSv3.1 vector of CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N. Exploitation requires a user to install a malicious Flatpak extension and use it with an application (AV:N, PR:N). The victim must specifically use a malicious extension in combination with a consuming application, and then launch that application (AC:H, UI:R). When Flatpak launches an application, it performs host-side file operations inside extension content directories using path-based APIs that follow symlinks without confinement; a malicious extension can place symlinks pointing at arbitrary host paths, which are followed both when checking for the.ref lock marker file and when iterating merge_dirs directories. These operations run at the invoking user's own privilege level rather than via the privileged system-helper (S:U). While the flaw allows probing for file/directory existence and disclosing filenames via reflected directory listings, no file contents are disclosed (C:N).
Low [CVE-2026-96283] Flatpak: flatpak: flatpak-system-helper cross-user cancelpull orphans another user's ongoing pull
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. Red Hat estimates the CVSSv3.1 vector of CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L. Exploitation requires the attacker to be a local, authenticated user on the same multi-user system as the victim, able to reach the org.freedesktop. Calling CancelPull on a pull ID belonging to another user removes that pull from the system-helper's internal tracking rather than actually cancelling it, and this requires no special preconditions beyond knowing/targeting another user's active pull, and no interaction from the victim (AC:L, UI:N). No data is disclosed or altered (C:N/I:N). The impact is a narrow availability effect: the targeted pull operation becomes untrackable and cannot subsequently be cancelled by its owner. This affects one specific in-progress operation rather than the system or service as a whole (A:L). Red Hat severity: Low — CVSS 3.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-862.
