Auth bypass in Tianma-If Edgeever
CVE-2026-108727
EdgeEver through 1.108.0 contains a missing authorization vulnerability in the Hono API memo-template routes that allows holders of scoped API tokens to bypass token scope restrictions because template handlers never call requireScopes. Attackers with a token lacking write:memos can save a template and invoke POST /api/v1/templates/:id/use to create memos, and list, modify, or delete templates in the token owner's workspace.
