{"schemaVersion":3,"id":"CVE-2026-12539","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Docker Sandboxes (sbx) blocks ICMP egress with an authorizer applied only at network-creation time, and does not re-apply it to networks rebuilt from disk when the Docker daemon restarts, so a restart-surviving sandbox forwards ICMP to arbitrary hosts. A workload inside a sandbox, which the threat model treats as untrusted, can therefore defeat the documented ICMP egress block to perform network reconnaissance and exfiltrate data over an ICMP covert channel, regardless of the configured allowlist.","dates":{"published":"2026-06-18T13:51:13.588Z","modified":"2026-08-13T13:33:36.104Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.7,"severity":"medium","version":"4.0","versionLabel":"v4.0","source":"NVD","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":5.1,"severity":"medium","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":5.7,"severity":"medium","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0014,"percentile":0.02975,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.0014},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0014,"percentile":0.02975}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0014,"percentile":null},{"date":"2026-10-07T00:00:0
