CVE-2026-92390
highpriority · track · 0EPSS 0.003 · 17 %ileDEFRUSEPSS · scored 2026-10-27
When invoked with `--remote-header-name` (`-J`), curl fails to preserve its documented anti-clobbering protection if an intermediate 103 Early Hints response precedes the final HTTP response, or if an `ETag` header is processed before `Content-Disposition` under `--etag-save`. This flaw allows an HTTP(S) server to overwrite an existing local file specified in the `Content-Disposition` header despite the presence of the `-J` non-overwrite constraint.
