{"id":"DEBIAN-CVE-2026-118655","details":"Echo is a Go web framework. Prior to 4.15.3 and 5.2.0, middleware.Static can decode an already decoded Request.URL.Path a second time. Double-encoded separators can consequently be reconstructed before filesystem resolution. This can reach a file under a guarded route when the static middleware is registered globally. This issue is fixed in 4.15.3 and 5.2.0.","modified":"2026-10-29T10:00:36.879085724Z","published":"2026-10-28T20:17:22.723Z","upstream":["CVE-2026-118655"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-118655"}],"affected":[{"package":{"name":"golang-github-labstack-echo","ecosystem":"Debian:12","purl":"pkg:deb/debian/golang-github-labstack-echo?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.11.1-1","4.11.1-2","4.12.0-1","4.2.1-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-118655.json"}},{"package":{"name":"golang-github-labstack-echo","ecosystem":"Debian:13","purl":"pkg:deb/debian/golang-github-labstack-echo?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.12.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-118655.json"}},{"package":{"name":"golang-github-labstack-echo","ecosystem":"Debian:14","purl":"pkg:deb/debian/golang-github-labstack-echo?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.12.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-118655.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
