{"id":"UBUNTU-CVE-2026-87107","details":"Consul and Consul Enterprise are vulnerable to an authorization bypass in the catalog deregistration path that may allow a local ACL token to delete peer-imported catalog objects. A caller with {{service:write}} or {{node:write}} permission may exploit this issue to remove services, checks, or nodes imported from a peered cluster without holding authority over the peer origin. This vulnerability (CVE-2026-87107) is fixed in Consul 2.0.4 and Consul Enterprise 1.21.18, 1.22.12 and 2.0.4.","modified":"2026-09-16T14:03:37.909241128Z","published":"2026-09-10T19:17:00Z","upstream":["CVE-2026-87107"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-87107"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-87107"}],"affected":[{"package":{"name":"consul","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/consul?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.4~dfsg-3"],"ecosystem_specific":{"binaries":[{"binary_name":"consul","binary_version":"0.6.4~dfsg-3"},{"binary_version":"0.6.4~dfsg-3","binary_name":"golang-github-hashicorp-consul-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-87107.json"}},{"package":{"name":"consul","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/consul?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.7~dfsg1-5ubuntu1","1.4.4~dfsg1-2ubuntu2","1.5.2+dfsg1-6","1.5.2+dfsg1-10","1.5.2+dfsg1-12","1.5.2+dfsg2-14"],"ecosystem_specific":{"binaries":[{"binary_name":"consul","binary_version":"1.5.2+dfsg2-14"},{"binary_version":"1.5.2+dfsg2-14","binary_name":"golang-github-hashicorp-consul-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-87107.json"}},{"package":{"name":"consul","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/consul?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.4+dfsg1-1","1.8.7+dfsg1-3"],"ecosystem_specific":{"binaries":[{"binary_name":"consul","binary_version":"1.8.7+dfsg1-3"},{"binary_name":"golang-github-hashicorp-consul-dev","binary_version":"1.8.7+dfsg1-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-87107.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L"},{"type":"Ubuntu","score":"medium"}]}
