Prior to version 6.23.0, instance template Incus is a system container and virtual machine manager. Prior to version 6.23.0, instance template files can be used to cause arbitrary read or writes as root on the host server. Incus allows for pongo2 templates within instances which can be used at various times in the instance lifecycle to template files inside of the instance. This particular

CVE-2026-33945 [CRITICAL] CWE-22 CVE-2026-33945: Incus is a system container and virtual machine manager. Incus instances have an option to provide c Incus is a system container and virtual machine manager. Incus instances have an option to provide credentials to systemd in the guest. For containers, this is handled through a shared directory.

CVE-2026-23954 [HIGH] CWE-22 CVE-2026-23954: Incus is a system container and virtual machine manager. Versions 6.21.0 and below allow a user with Incus is a system container and virtual machine manager. Versions 6.21.0 and below allow a user with the ability to launch a container with a custom image (e.g a member of the ‘incus’ group) to use directory traversal or symbolic links in the templating functionality to achieve host arbitrary file read, and host arbitrary file write. This ultimately re

CVE-2026-23953 [HIGH] CWE-93 CVE-2026-23953: Incus is a system container and virtual machine manager. In versions 6.20.0 and below, a user with t Incus is a system container and virtual machine manager. In versions 6.20.0 and below, a user with the ability to launch a container with a custom YAML configuration (e.g a member of the ‘incus’ group) can create an environment variable containing newlines, which can be used to add additional configuration items in the container’s lxc.conf due to newli

CVE-2026-33898 [HIGH] CWE-287 CVE-2026-33898: Incus is a system container and virtual machine manager. Prior to version 6.23.0, the web server spa Incus is a system container and virtual machine manager. Prior to version 6.23.0, the web server spawned by `incus webui` incorrectly validates the authentication token such that an invalid value will be accepted. `incus webui` runs a local web server on a random localhost port. For authentication, it provides the user with a URL containing an authent

CVE-2026-33711 [HIGH] CWE-61 CVE-2026-33711: Incus is a system container and virtual machine manager. Incus provides an API to retrieve VM screen Incus is a system container and virtual machine manager. Incus provides an API to retrieve VM screenshots. That API relies on the use of a temporary file for QEMU to write the screenshot to which is then picked up and sent to the user prior to deletion. As versions prior to 6.23.0 use predictable paths under /tmp for this, an attacker with local access

CVE-2025-64507 [HIGH] CWE-269 CVE-2025-64507: Incus is a system container and virtual machine manager. An issue in versions prior to 6.0.6 and 6.1 Incus is a system container and virtual machine manager. An issue in versions prior to 6.0.6 and 6.19.0 affects any Incus user in an environment where an unprivileged user may have root access to a container with an attached custom storage volume that has the `security.shifted` property set to `true` as well as access to the host as an unprivileged us

CVE-2026-24767 [MEDIUM] CWE-918 CVE-2026-24767: NocoDB is software for building databases as spreadsheets. Prior to version 0.301.0, a blind Server- NocoDB is software for building databases as spreadsheets. Prior to version 0.301.0, a blind Server-Side Request Forgery (SSRF) vulnerability exists in the `uploadViaURL` functionality due to an unprotected `HEAD` request. While the subsequent file retrieval logic correctly enforces SSRF protections, the initial metadata request executes without val

CVE-2025-52890 [HIGH] CWE-863 CVE-2025-52890: Incus is a system container and virtual machine manager. When using an ACL on a device connected to Incus is a system container and virtual machine manager. When using an ACL on a device connected to a bridge, Incus versions 6.12 and 6.13generates nftables rules that partially bypass security options `security.mac_filtering`, `security.ipv4_filtering` and `security.ipv6_filtering`. This can lead to ARP spoofing on the bridge and to fully spoof anothe

CVE-2026-33743 [MEDIUM] CWE-770 CVE-2026-33743: Incus is a system container and virtual machine manager. Prior to version 6.23.0, a specially crafte Incus is a system container and virtual machine manager. Prior to version 6.23.0, a specially crafted storage bucket backup can be used by an user with access to Incus' storage bucket feature to crash the Incus daemon. Repeated use of this attack can be used to keep the server offline causing a denial of service of the control plane API. This does n

CVE-2026-41684 [MEDIUM] CWE-476 CVE-2026-41684: Incus is a system container and virtual machine manager. Prior to version 7.0.0, backup.GetInfo() tr Incus is a system container and virtual machine manager. Prior to version 7.0.0, backup.GetInfo() trusts the inline backup/index.yaml config when present and only falls back to parsing the legacy backup/container/backup.yaml file if result.Config == nil. As a result, an archive can carry a valid inline config that passes the initial import preflight

CVE-2026-40251 [MEDIUM] CWE-129 CVE-2026-40251: Incus is a system container and virtual machine manager. In versions before 7.0.0, missing validatio Incus is a system container and virtual machine manager. In versions before 7.0.0, missing validation logic in the storage volume import logic allows an authenticated user with access to the storage volume feature to cause the Incus daemon to crash.

CVE-2026-41647 [MEDIUM] CWE-476 CVE-2026-41647: Incus is a system container and virtual machine manager. Prior to version 7.0.0, a missing error han Incus is a system container and virtual machine manager. Prior to version 7.0.0, a missing error handling could lead an authenticated Incus user to cause a daemon crash through the import of a truncated storage bucket backup file. This issue has been patched in version 7.0.0.

CVE-2026-41648 [MEDIUM] CWE-770 CVE-2026-41648: Incus is a system container and virtual machine manager. Prior to version 7.0.0, user provided image Incus is a system container and virtual machine manager. Prior to version 7.0.0, user provided image and backup tarballs would be unpacked and YAML files parsed without any size restrictions. This was making it easy for an authenticated user to provide a crafted image or backup tarball that when parsed by Incus would lead to a very large YAML docume
