Untrusted code inside a sandbox could use a case-variant hostname to reach the genuine provider endpoint while bypassing response masking. If a user completed the OAuth flow, the provider's access and refresh tokens could be returned unmasked to the sandbox, exposing host-managed credentials.","published":"2026-10-08T19:16:57.000Z","lastModified":"2026-10-08T20:46:35.000Z","status":"Awaiting Analysis","sourceIdentifier":"security@docker.com","cvss":{"version":"4.0","score":6.7,"severity":"MEDIUM","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/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/M"},"cwe":["CWE-178"],"affected":[],"epss":{"score":0.00127,"percentile":0.02348,"date":"2026-10-27","history":[{"date":"2026-10-09","score":0.00127,"percentile":0.02079}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.13%).
