OpenStack Neutron has an Incorrect Authorization issue

CVE-2026-49299 / GHSA-xv24-hxh9-2hh9

More information

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.

Severity

• CVSS Score: 5.3 / 10 (Medium)

OpenStack Neutron: Neutron port RBAC policy bypass allows project managers to set trusted device owners on shared networks

CVE-2026-50266 / GHSA-qmc5-gv6v-8p22

More information

Details

In OpenStack Neutron before 28.0.1, a project manager can create or update a port on a shared network owned by another project and set device_owner to a value that has "network:" at the beginning ("network:dhcp" for example). The default port RBAC policies incorrectly included PROJECT_MANAGER without requiring network ownership, allowing any project manager to obtain trusted network-service port behavior on shared networks. Depending on backend and deployment, this can bypass anti-spoofing and security group protections, enabling DHCP, MAC, or IP spoofing against other tenants on the shared network. This is a regression of CVE-2015-5240 (OSSA-2015-018).

Severity

• CVSS Score: 2.2 / 10 (Low)
• Vector String: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:N
