{"id":"UBUNTU-CVE-2026-122132","details":"go-chi chi 5.2.2 through 5.5.0 contains an open redirect vulnerability in the RedirectSlashes middleware that allows attackers to redirect victims to external hosts by embedding tab characters in request paths. Attackers can craft links with a URL-encoded tab, which browsers strip from the 301 Location header and resolve as a protocol-relative URL, bypassing the fix for CVE-2025-69725.","modified":"2026-11-06T01:00:19.973912145Z","published":"2026-11-05T00:00:00Z","upstream":["CVE-2026-122132"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-122132"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-122132"},{"type":"REPORT","url":"https://github.com/go-chi/chi/security/advisories/GHSA-mqqf-5wvp-8fh8"},{"type":"REPORT","url":"https://github.com/go-chi/chi/pull/1238"},{"type":"REPORT","url":"https://github.com/go-chi/chi"},{"type":"REPORT","url":"https://github.com/go-chi/chi/blob/v5.5.0/middleware/strip.go#L41-L69"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/go-chi-chi-5.2.2-through-5.5.0-open-redirect-via-redirectslashes-middleware"}],"affected":[{"package":{"name":"golang-github-go-chi-chi","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-chi-chi?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.5.1-2","5.0.7-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-go-chi-chi-dev","binary_version":"5.0.7-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-122132.json"}},{"package":{"name":"golang-github-go-chi-chi","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-chi-chi?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.7-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-go-chi-chi-dev","binary_version":"5.0.7-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-122132.json"}},{"package":{"name":"golang-github-go-chi-chi","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/golang-github-go-chi-chi?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.3-1","5.3.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"5.3.0-1","binary_name":"golang-github-go-chi-chi-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-122132.json"}},{"package":{"name":"golang-github-go-chi-chi","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-chi-chi?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.0-1","5.2.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-go-chi-chi-dev","binary_version":"5.2.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-122132.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
