{"id":"CVE-2026-49299","details":"In OpenStack Neutron before 28.0.1, the tagging controller enforces plural policy action names on single-tag write operations while the defined policy rules use singular names. The mismatched names evaluate as allowed under the default policy, permitting a project reader to create and update tags on same-project resources. Deployments running Neutron 26.0.0 or later are affected.","aliases":["GHSA-xv24-hxh9-2hh9"],"modified":"2026-07-08T08:12:35.632909174Z","published":"2026-05-28T21:53:03.408Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49299.json","cna_assigner":"mitre","cwe_ids":["CWE-863"]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/06/02/7"},{"type":"WEB","url":"https://opendev.org/openstack/neutron"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2026/05/28/8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49299.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49299"},{"type":"REPORT","url":"https://bugs.launchpad.net/bugs/2150132"},{"type":"FIX","url":"https://review.opendev.org/c/openstack/neutron/+/989099"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://opendev.org/openstack/neutron","events":[{"introduced":"96a445dee8363976333aed121358a4b86f9428e0"},{"fixed":"68346f102f34be9345e8e590b68622101a9c4922"},{"introduced":"46f4ef447537d80bff2bb64da6a61fff40e8fcc3"},{"fixed":"6e846c1a2d5ad40f767e87b6c8ddb14b509ba5d7"},{"introduced":"eb9dd526a3c4ba0ffbb69d06cc387c86ca755d42"},{"fixed":"8d11b5e2fd0f72840fc827ffe4ab4f3fa89221d0"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"26.0.0"},{"fixed":"26.0.4"},{"introduced":"27.0.0"},{"fixed":"27.0.3"},{"introduced":"28.0.0"},{"fixed":"28.0.1"}]}}],"versions":["26.0.3","27.0.2","28.0.0.0rc2","28.0.0","26.0.2","27.0.1","27.0.0.0rc1","27.0.0","26.0.1","26.0.0.0rc2","26.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49299.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
