Affected packages
• PyPI neutron: >= 28.0.0, < 28.0.1 → fixed in 28.0.1

• PyPI neutron: >= 26.0.0, < 26.0.4 → fixed in 26.0.4
Description
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.
