Name of the Vulnerable Software and Affected Versions OpenStack Neutron versions 26.0.0 through 28.0.0

Description The tagging controller enforces plural policy action names on single-tag write operations, whereas the defined policy rules use singular names. This mismatch causes the default policy to evaluate the actions as allowed, enabling a project reader to create and update tags on resources within the same project.

Recommendations Update to version 28.0.1.
