Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16033 exists.\n\nAffected product: Canonical LXD. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-16033/ (Markdown: https://insights.sbomify.com/CVE-2026-16033/index.md)","id":"CVE-2026-16033","markdown":"https://insights.sbomify.com/CVE-2026-16033/index.md","name":"CVE-2026-16033","record":{"aliases":["DEBIAN-CVE-2026-16033","GHSA-9hcm-hxh5-7xxh","UBUNTU-CVE-2026-16033"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"LXD container manager","requires_auth":"low_privilege","summary":"Attackers can read or write arbitrary host files via malicious image templates in LXD, compromising host integrity and confidentiality.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"lxd","vendor":"canonical"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A path traversal vulnerability in LXD allows an attacker to achieve arbitrary host file read or unconstrained file creation. When processing image metadata templates, LXD fails to properly sanitize or restrict template file paths from escaping the instance templates directory (specifically affecting virtual machine / QEMU driver execution paths). An attacker can exploit this flaw by providing a crafted image archive with malicious template directives containing path traversal sequences, causing LXD to access or write files outside the intended template directory on the host system.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Arbitrary file read+write on host via templates/ symlink in malicious image","id":"CVE-2026-16033","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"miniOrange 2FA \u003c 6.2.7 - Subscriber+ Arbitrary-Recipient OTP Send","id":"CVE-2026-16035"},"packages":[],"prev":{"headline":"LWS Optimize \u003c 4.1.2 - Unauthenticated Stored XSS via Real User Monitoring","id":"CVE-2026-16032"},"products":["LXD"],"published":"2026-08-12","related":[{"cvss_score":9.9,"headline":"Instance template path traversal allows arbitrary host file write as root","id":"CVE-2026-66897","kev_date_added":null,"published":"2026-08-24"},{"cvss_score":9.9,"headline":"Cross-project cluster migration bypasses project restrictions via cluster notification flag","id":"CVE-2026-62420","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Arbitrary File Read/Write: metadata.yaml symlink in image allows host filesystem access as root","id":"CVE-2026-63293","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Root RCE via image backup.yaml symlink","id":"CVE-2026-63294","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Project restriction bypass via instance migration config override","id":"CVE-2026-63296","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Cross-project instance copy bypasses target project restrictions via TOCTOU in config merge","id":"CVE-2026-63297","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Cross-project instance move bypasses all project restrictions allowing host command execution","id":"CVE-2026-63300","kev_date_added":null,"published":"2026-08-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-13","vendors":["Canonical"]},"summary":"Attackers can read or write arbitrary host files via malicious image templates in LXD, compromising host integrity and confidentiality.","url":"https://insights.sbomify.com/CVE-2026-16033/"}
