It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-49237 in the wild and no public exploit code.\n\nAffected product: Canonical Multipass. 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-2026-49237/ (Markdown: https://insights.sbomify.com/CVE-2026-49237/index.md)","id":"CVE-2026-49237","markdown":"https://insights.sbomify.com/CVE-2026-49237/index.md","name":"CVE-2026-49237","record":{"aliases":["GHSA-r2xg-x32f-23c5"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Virtualization tool","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges to root by replacing writable auxiliary binaries invoked by the root daemon in Canonical Multipass for macOS.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"multipass","vendor":"canonical"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"An issue was discovered in Canonical Multipass for macOS before version 1.16.3 due to an incomplete fix for CVE-2025-5199. While the patch in version 1.16.0 updated the ownership of the multipassd daemon binary to root:wheel, five co-located binaries (multipass, qemu-img, qemu-system-aarch64, qemu-system-x86_64, and sshfs_server) in /Library/Application Support/com.canonical.multipass/bin/ retain ownership by the installing user and remain writable. Because the root LaunchDaemon (com.canonical.multipassd.plist) configures a PATH environment variable that prioritizes this user-writable directory and invokes these auxiliary binaries by their bare names, a local attacker can replace an auxiliary binary (such as qemu-img) with a malicious wrapper. When the root daemon subsequently triggers the binary during routine execution (e.g., via multipass launch), the malicious code executes with root privileges, leading to local privilege escalation.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Local Privilege Escalation in Canonical Multipass","id":"CVE-2026-49237","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"SFTP Server VM Escape in Canonical Multipass","id":"CVE-2026-49238"},"packages":[],"prev":{"headline":"Routinator crashes on specifically crafted RRDP XML files","id":"CVE-2026-49235"},"products":["Multipass"],"published":"2026-05-28","related":[{"cvss_score":8.8,"headline":"Windows version of Multipass unauthenticated localhost tcp control socket can perform mounts","id":"CVE-2021-3626","kev_date_added":null,"published":"2021-10-01"},{"cvss_score":8.8,"headline":"MacOS version of Multipass incorrect owner for application directory","id":"CVE-2021-3747","kev_date_added":null,"published":"2021-10-01"},{"cvss_score":8.4,"headline":"SFTP Server VM Escape in Canonical Multipass","id":"CVE-2026-49238","kev_date_added":null,"published":"2026-05-28"},{"cvss_score":7.3,"headline":"LPE on Multipass for macOS","id":"CVE-2025-5199","kev_date_added":null,"published":"2025-07-11"}],"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-28","vendors":["Canonical"]},"summary":"Local attackers can escalate privileges to root by replacing writable auxiliary binaries invoked by the root daemon in Canonical Multipass for macOS.","url":"https://insights.sbomify.com/CVE-2026-49237/"}
