Critical 9.9
Instance template path traversal allows arbitrary host file write as root
A path traversal vulnerability in LXD's instance template processing allows an attacker with container edit permissions, or any user launching a crafted image, to overwrite arbitrary files on the host system as root. When processing target template paths spec…

Critical 9.9
Incus has an arbitrary file write on its client due to trusted image hash
Incus is a system container and virtual machine manager. Prior to version 7.2.0, an arbitrary file write exists in the Incus client when a malicious image server returns a crafted `Incus-Image-Hash` header. This can lead to arbitrary command execution as root…

Critical 9.9
Incus has an argument injection in backup compression algorithm leading to AFW and ACE
Incus is a system container and virtual machine manager. Prior to version 7.1.0, improper validation of user-provided backup compression algorithm leads to argument injection in the constructed command line. This leads to an arbitrary file write on the host, …

Incus has arbitrary file read+write on host via templates/ symlink in malicious image
Incus is a system container and virtual machine manager. Prior to version 7.2.0, a specially crafted image or instance backup can be used to read or create/write arbitrary files on the host; possibly leading to arbitrary command execution. Version 7.2.0 patch…

Critical 9.9
Incus has a restricted project bypass leading to arbitrary command execution
Incus is a system container and virtual machine manager. Prior to version 7.2.0, instance snapshots ignore the `restricted.containers.lowlevel=block` setting; allowing for arbitrary command execution on the Incus server by abusing lowlevel hooks such as `raw.…

Critical 9.9
Incus has an arbitrary file write on host via `exec-output` symlink in crafted image
Incus is a system container and virtual machine manager. Prior to version 7.2.0, the `record-output` parameter of the `/instances/$name/exec` endpoint stores the output of the command in the `exec-output` directory of the instance. If `exec-output` is a symli…

Critical 9.9
Incus has an arbitrary file read+write on host via rootfs/ symlink in malicious image
Incus is a system container and virtual machine manager. Prior to version 7.2.0, a specially crafted image can be used to read or create/write arbitrary files on the host; possibly leading to arbitrary command execution. Version 7.2.0 fixes the issue.

Critical 9.9
Path traversal via unvalidated instance name in backup tarball restore enables root file write / RCE
A path traversal vulnerability in LXD allows an attacker to manipulate file system paths during backup import and restore operations. When importing or restoring a backup archive, LXD fails to validate instance and storage volume names contained within the ar…

Critical 9.9
Arbitrary File Read/Write: metadata.yaml symlink in image allows host filesystem access as root
A link following vulnerability in LXD allows an attacker to achieve arbitrary file read and write operations on the host system. When importing or unpacking an image archive, LXD fails to validate whether the metadata.yaml file is a symbolic link. An attacker…

Critical 9.9
Root RCE via image backup.yaml symlink
A link following vulnerability in LXD allows an attacker to achieve root command execution on the host system. During the import or unpacking of crafted image or backup archives, LXD fails to properly validate and confine the backup.yaml file when it exists a…

Critical 9.9
Project restriction bypass via instance migration config override
An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass target project restrictions during instance migration. When migrating an instance to a target project, LXD accepts configuration overrides without validating the new confi…

Critical 9.9
Cross-project instance copy bypasses target project restrictions via TOCTOU in config merge
An authorization bypass vulnerability in LXD due to a timing flaw during configuration merging allows an authenticated attacker to bypass target project restrictions during cross-project instance copies. When copying an instance to a target project, LXD perfo…

Critical 9.9
Cross-project cluster migration bypasses project restrictions via cluster notification flag
An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass target project security restrictions during cross-project instance migrations. When moving an instance cross-project to a different cluster member via POST /1.0/instances/…

Critical 9.9
Cross-project instance move bypasses all project restrictions allowing host command execution
An improper validation vulnerability in the instancePostMigration function in lxd/instance_post.go of LXD allows an authenticated attacker with can_create_instances permissions on a restricted project to bypass project-level security restrictions. When migrat…

Update of type field in restricted TLS certificate allows privilege escalation to cluster admin
In Canonical LXD versions 4.12 through 6.7, the doCertificateUpdate function in lxd/certificates.go does not validate the Type field when handling PUT/PATCH requests to /1.0/certificates/{fingerprint} for restricted TLS certificate users, allowing a remote au…

Critical 9.1
Importing a crafted backup leads to project restriction bypass
In Canonical LXD before 6.8, the backup import path validates project restrictions against backup/index.yaml in the supplied tar archive but creates the instance from backup/container/backup.yaml, a separate file in the same archive that is never checked agai…
