{"id":"UBUNTU-CVE-2026-107363","details":"In OpenStack Zaqar before 23.0.1, the WebSocket transport fails to bind the project identifier in subsequent requests to the project authenticated by the Keystone token. An authenticated user with a valid token for one project may substitute another project's UUID to enumerate, inspect, create, or delete queues belonging to that project, resulting in unauthorized disclosure, modification, or loss of queue data. Only deployments using the WebSocket transport with Keystone authentication are affected.","modified":"2026-10-08T19:47:05.343991280Z","published":"2026-10-08T00:00:00Z","upstream":["CVE-2026-107363"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-107363"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-107363"},{"type":"REPORT","url":"https://security.openstack.org/ossa/OSSA-2026-043.html"},{"type":"REPORT","url":"https://bugs.launchpad.net/ossa/+bug/2161402"},{"type":"REPORT","url":"https://launchpad.net/bugs/2161402"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2026/10/07/30"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2026/10/07/31"}],"affected":[{"package":{"name":"zaqar","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/zaqar?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.0-2","1.0.0-6","2.0.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.0-1","binary_name":"python-zaqar"},{"binary_name":"zaqar-common","binary_version":"2.0.0-1"},{"binary_name":"zaqar-server","binary_version":"2.0.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107363.json"}},{"package":{"name":"zaqar","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/zaqar?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.0-0ubuntu1","6.0.0~b1-0ubuntu1","6.0.0~b2-0ubuntu2","6.0.0~b3-0ubuntu1","6.0.0~rc1-0ubuntu1","6.0.0-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"6.0.0-0ubuntu1","binary_name":"python-zaqar"},{"binary_name":"zaqar-common","binary_version":"6.0.0-0ubuntu1"},{"binary_name":"zaqar-server","binary_version":"6.0.0-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107363.json"}},{"package":{"name":"zaqar","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/zaqar?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.0.0-0ubuntu1","10.0.0~b1~git2019121815.55c73e22-0ubuntu1","10.0.0~b2~git2020021011.22c457a5-0ubuntu1","10.0.0~b3~git2020032614.22c457a5-0ubuntu1","10.0.0~b3~git2020041014.22c457a5-0ubuntu1","10.0.0-0ubuntu0.20.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-zaqar","binary_version":"10.0.0-0ubuntu0.20.04.1"},{"binary_name":"zaqar-common","binary_version":"10.0.0-0ubuntu0.20.04.1"},{"binary_name":"zaqar-server","binary_version":"10.0.0-0ubuntu0.20.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107363.json"}},{"package":{"name":"zaqar","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/zaqar?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["13.0.0-0ubuntu1","13.0.0+git2021120910.a7593240-0ubuntu1","13.0.0+git2022011310.1726ac41-0ubuntu1","14.0.0-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-zaqar","binary_version":"14.0.0-0ubuntu1"},{"binary_name":"zaqar-common","binary_version":"14.0.0-0ubuntu1"},{"binary_name":"zaqar-server","binary_version":"14.0.0-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107363.json"}},{"package":{"name":"zaqar","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/zaqar?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["17.0.0-0ubuntu1","17.0.0+git2024020808.2c859275-0ubuntu1","18.0.0~rc1-0ubuntu1","18.0.0-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-zaqar","binary_version":"18.0.0-0ubuntu1"},{"binary_version":"18.0.0-0ubuntu1","binary_name":"zaqar-common"},{"binary_name":"zaqar-server","binary_version":"18.0.0-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107363.json"}},{"package":{"name":"zaqar","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/zaqar?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["21.0.0-0ubuntu1","21.0.0+git20260121.32.59a7a63d-0ubuntu1","22.0.0~rc1-0ubuntu2","22.0.0-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"22.0.0-0ubuntu1","binary_name":"python3-zaqar"},{"binary_version":"22.0.0-0ubuntu1","binary_name":"zaqar-common"},{"binary_name":"zaqar-server","binary_version":"22.0.0-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107363.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
