CVE-2026-18584Hinoki check available

Unauthenticated eSIM profile control via nginx bypass

Published Aug 3, 2026 · Updated Aug 3, 2026

Improper authorization in affected GL.iNet router eSIM LPA APIs allows remote attackers on the LAN to access and alter eSIM profiles. The /sdk/v1 nginx location omits access_by_lua_file, so LPA methods receive requests without a credential, cookie or token. LAN access is required; exposed operations disclose identifiers and logs and permit profile disablement, deletion or installation, including cellular WAN interruption.
