{"id":"UBUNTU-CVE-2026-92390","details":"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.","modified":"2026-10-17T13:01:17.582069810Z","published":"2026-10-14T06:00:00Z","related":["USN-8927-1"],"upstream":["CVE-2026-92390"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-92390"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-92390"},{"type":"REPORT","url":"https://curl.se/docs/CVE-2026-92390.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8927-1"}],"affected":[{"package":{"name":"curl","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/curl?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.32.0-1ubuntu1","7.33.0-1ubuntu1","7.34.0-1ubuntu1","7.35.0-1ubuntu1","7.35.0-1ubuntu2","7.35.0-1ubuntu2.1","7.35.0-1ubuntu2.2","7.35.0-1ubuntu2.3","7.35.0-1ubuntu2.5","7.35.0-1ubuntu2.6","7.35.0-1ubuntu2.7","7.35.0-1ubuntu2.8","7.35.0-1ubuntu2.9","7.35.0-1ubuntu2.10","7.35.0-1ubuntu2.11","7.35.0-1ubuntu2.12","7.35.0-1ubuntu2.13","7.35.0-1ubuntu2.14","7.35.0-1ubuntu2.15","7.35.0-1ubuntu2.16","7.35.0-1ubuntu2.17","7.35.0-1ubuntu2.19","7.35.0-1ubuntu2.20","7.35.0-1ubuntu2.20+esm2","7.35.0-1ubuntu2.20+esm3","7.35.0-1ubuntu2.20+esm4","7.35.0-1ubuntu2.20+esm5","7.35.0-1ubuntu2.20+esm6","7.35.0-1ubuntu2.20+esm7","7.35.0-1ubuntu2.20+esm8","7.35.0-1ubuntu2.20+esm9","7.35.0-1ubuntu2.20+esm10","7.35.0-1ubuntu2.20+esm11","7.35.0-1ubuntu2.20+esm12","7.35.0-1ubuntu2.20+esm13","7.35.0-1ubuntu2.20+esm14","7.35.0-1ubuntu2.20+esm15","7.35.0-1ubuntu2.20+esm16","7.35.0-1ubuntu2.20+esm17","7.35.0-1ubuntu2.20+esm18","7.35.0-1ubuntu2.20+esm19","7.35.0-1ubuntu2.20+esm20","7.35.0-1ubuntu2.20+esm21","7.35.0-1ubuntu2.20+esm22","7.35.0-1ubuntu2.20+esm23","7.35.0-1ubuntu2.20+esm24"],"ecosystem_specific":{"binaries":[{"binary_name":"curl","binary_version":"7.35.0-1ubuntu2.20+esm24"},{"binary_name":"libcurl3","binary_version":"7.35.0-1ubuntu2.20+esm24"},{"binary_name":"libcurl3-gnutls","binary_version":"7.35.0-1ubuntu2.20+esm24"},{"binary_name":"libcurl3-nss","binary_version":"7.35.0-1ubuntu2.20+esm24"}],"priority_reason":"Upstream
