The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).","id":"ALPINE-CVE-2026-14199","modified":"2026-11-04T22:30:02.827577139Z","published":"2026-09-02T16:17:14.517Z","references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-14199"}],"schema_version":"1.9.2","severity":[{"score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","type":"CVSS_V3"}],"upstream":["CVE-2026-14199"]}
