OpenStack Neutron has an Incorrect Authorization issue

Source: GitHub Advisory Database (reviewed) Moderate CVE-2026-49299

Packages

EcosystemPackageAffectedFixed in
PyPI neutron >= 28.0.0, < 28.0.1 28.0.1
PyPI neutron >= 27.0.0, < 27.0.3 27.0.3

Details

As written in the advisory (Markdown source, shown as plain text).

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.
