{"schemaVersion":3,"id":"CVE-2026-105452","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Docker Sandboxes could forward a client-supplied credential alongside a credential injected by the host egress proxy. The proxy removed alternate credentials only when their values matched known sentinel values, so untrusted code in an authorized sandbox could supply an unrecognized credential in another supported authentication header. For affected upstream services, this could authenticate the request to an attacker-controlled account and expose data included in the request.","dates":{"published":"2026-10-08T18:49:37.331Z","modified":"2026-10-08T19:29:41.004Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.9,"severity":"medium","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":5.9,"severity":"medium","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/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":5.9,"severity":"medium","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/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":0.00143,"percentile":0.03235,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-09T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00143,"percentile":0.03235}],"last30":[{"date":"2026-10-09T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00143,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00143,"percentile":0.03235}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-200","name":"Exposure
