CVE-2026-49299

CVE-2026-49299

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
