CVE-2026-71280
go-shiori's DownloadBookmark (internal/core/download.go) fetches a caller-supplied bookmark URL using a plain http.Client with no custom DialContext or destination-IP validation (no IsLoopback, IsPrivate, IsUnspecified, or IsLinkLocalUnicast checks).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
