Summary
OpenStack Octavia through 18.0.0 mishandles QoS policy authorization. By associating another project's QoS policy with an amphora, an authenticated user may prevent deletion of that policy.
Risk Assessment
This could lead to disruption in QoS policy management and potentially cause availability or security issues.
Recommendation
Update OpenStack Octavia to a patched version and monitor QoS policy permissions.
Other vulnerabilities in OpenStack Octavia
See all- CVE-2026-94572Critical
In OpenStack Octavia before 18.0.1, the Amphora provider driver did not validate the listener and pool tls_ciphers field for control characters. The value is written verbatim into the HAProxy configuration generated on the amphora, allowing an authenticated project member who owns a TLS-enabled load balancer to embed a newline and inject arbitrary HAProxy configuration directives.
- CVE-2026-94571Critical
In OpenStack Octavia before 18.0.1, the Amphora provider driver did not reject control characters in the L7 policy redirect_url and redirect_prefix fields. The RFC 3986 URL validator percent-encodes control characters before validating, so newlines passed structural checks, but Octavia stored and wrote the raw unencoded value directly into the HAProxy configuration generated on the amphora.
Original NVD description (English source)
OpenStack Octavia through 18.0.0 mishandles quality of service (QoS) policy authorization. By associating another project's QoS policy with an amphora, an authenticated user may prevent deletion of that policy. All Octavia deployments are affected.
