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-2026-8933 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 22.04 LTS. 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-2026-8933/ (Markdown: https://insights.sbomify.com/CVE-2026-8933/index.md)","id":"CVE-2026-8933","markdown":"https://insights.sbomify.com/CVE-2026-8933/index.md","name":"CVE-2026-8933","record":{"aliases":["DEBIAN-CVE-2026-8933","GHSA-fxqr-j4gx-622c","UBUNTU-CVE-2026-8933"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Ubuntu snapd","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges to root in Ubuntu systems using snap-confine with set-capabilities due to a flaw in execution environment setup.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[],"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-250","name":"Execution with Unnecessary Privileges"}],"description":"A local privilege escalation vulnerability exists in snap-confine, a set-capabilities core component used internally by Canonical snapd to construct the secure execution environment for snap applications. This vulnerability uniquely affects versions of snap-confine configured with set-capabilities (rather than standard set-uid-root installations).\nDue to a flaw in how privilege boundaries or security sandboxes are initialized when the binary runs under limited ambient capabilities, a local, unprivileged attacker can exploit this behavior to bypass intended restrictions and execute arbitrary code. Successful exploitation allows the local user to elevate their privileges to full root authority.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-17","github_poc":2,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-17T01:42:31Z","kind":"github_poc","ref":"https://github.com/songzzzz/CVE-2026-8933","stars":0,"title":null},{"date":"2026-10-23T08:24:27Z","kind":"github_poc","ref":"https://github.com/yifengchen-cc/CVE-2026-8933","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"snap-confine Local Privilege Escalation via Capabilities Misconfiguration or Flaw in Execution Environment Setup","id":"CVE-2026-8933","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":"Cross-Project Information Leakage in Google App Engine UI","id":"CVE-2026-8934"},"packages":[],"prev":{"headline":"incomplete mTLS config matching in conn reuse","id":"CVE-2026-8932"},"products":["Ubuntu 22.04 LTS","Ubuntu 24.04 LTS","Ubuntu 26.04 LTS"],"published":"2026-07-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-22","vendors":["Canonical"]},"summary":"Local attackers can escalate privileges to root in Ubuntu systems using snap-confine with set-capabilities due to a flaw in execution environment setup.","url":"https://insights.sbomify.com/CVE-2026-8933/"}
