{"id":"GHSA-xv24-hxh9-2hh9","summary":"OpenStack Neutron has an Incorrect Authorization issue","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":["CVE-2026-49299","PYSEC-2026-2678"],"modified":"2026-07-13T16:42:31.204793899Z","published":"2026-05-29T00:38:33Z","database_specific":{"cwe_ids":["CWE-863"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-07-02T18:50:58Z","nvd_published_at":"2026-05-28T22:17:02Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49299"},{"type":"WEB","url":"https://bugs.launchpad.net/bugs/2150132"},{"type":"PACKAGE","url":"https://github.com/openstack/neutron"},{"type":"WEB","url":"https://review.opendev.org/c/openstack/neutron/+/989099"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2026/05/28/8"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/06/02/7"}],"affected":[{"package":{"name":"neutron","ecosystem":"PyPI","purl":"pkg:pypi/neutron"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"28.0.0"},{"fixed":"28.0.1"}]}],"versions":["28.0.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-xv24-hxh9-2hh9/GHSA-xv24-hxh9-2hh9.json"}},{"package":{"name":"neutron","ecosystem":"PyPI","purl":"pkg:pypi/neutron"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"27.0.0"},{"fixed":"27.0.3"}]}],"versions":["27.0.0","27.0.1","27.0.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-xv24-hxh9-2hh9/GHSA-xv24-hxh9-2hh9.json"}},{"package":{"name":"neutron","ecosystem":"PyPI","purl":"pkg:pypi/neutron"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"26.0.0"},{"fixed":"26.0.4"}]}],"versions":["26.0.0","26.0.1","26.0.2","26.0.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-xv24-hxh9-2hh9/GHSA-xv24-hxh9-2hh9.json"}}],"schema_version":"1.9.0","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"}]}
