{"id":"UBUNTU-CVE-2026-50151","details":"oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, registry/remote/repository.go in blobStore.completePushAfterInitialPost follows a registry-controlled Location header during monolithic blob upload and reuses the Authorization header from the initial POST request for the subsequent PUT request, allowing a malicious registry to return a cross-host Location and receive the caller's credentials at an attacker-controlled endpoint. This issue is fixed in version 2.6.1.","modified":"2026-07-29T10:18:37.895925568Z","published":"2026-07-17T20:17:00Z","upstream":["CVE-2026-50151"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-50151"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-50151"},{"type":"REPORT","url":"https://github.com/oras-project/oras-go/security/advisories/GHSA-jxpm-75mh-9fp7"},{"type":"REPORT","url":"https://github.com/oras-project/oras-go/pull/1152"}],"affected":[{"package":{"name":"golang-oras-oras-go","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-oras-oras-go?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.1-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-oras-oras-go-dev","binary_version":"1.1.1-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-50151.json"}},{"package":{"name":"golang-oras-oras-go","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/golang-oras-oras-go?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.0-1","2.6.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.6.0-1","binary_name":"golang-oras-oras-go-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-50151.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
