{"schema":"threatline.record/2","record":{"id":"CVE-2026-8933","aliases":[],"summary":"snap-confine Local Privilege Escalation via Capabilities Misconfiguration or Flaw in Execution Environment Setup","details":"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.","categories":["Unclassified"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-8933","source_modified_at":"2026-07-22T18:28:05.924Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":null,"vendor":null,"versions":[{"status":"affected","version":"2.75.0","lessThan":"2.76.1","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-8933","source_modified_at":"2026-07-22T18:28:05.924Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Ubuntu 26.04 LTS","vendor":"Canonical","versions":[{"status":"unaffected","version":"2.76+ubuntu26.04.3","versionType":"dpkg"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-8933","source_modified_at":"2026-07-22T18:28:05.924Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Ubuntu 24.04 LTS","vendor":"Canonical","versions":[{"status":"unaffected","version":"2.76+ubuntu24.04.1","versionType":"dpkg"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-8933","source_modified_at":"2026-07-22T18:28:05.924Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Ubuntu 22.04 LTS","vendor":"Canonical","versions":[{"status":"unaffected","version":"2.76+ubuntu22.04.1","versionType":"dpkg"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-8933","source_modified_at":"2026-07-22T18:28:05.924Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":null,"ecosystem":null},"version":"2.76.1","basis":"first unaffected version stated in the CVE record"}],"cvss":7.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00178,"percentile":0.06957,"score_date":"2026-10-23"},"published_at":"2026-07-21T14:02:19.758Z","modified_at":"2026-07-22T18:28:05.924Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-8933","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-07-22T18:28:05.924Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-8933","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://ubuntu.com/security/CVE-2026-8933","tags":["vdb-entry","issue-tracking"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-07-22T18:15:11.199548Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-07-22T18:28:05.924Z","content_hash":"6492452ff33b0fab8a3738b76f60b06380752f8c7f73729ba6aaa4c210b354f1"}}
