Affected: OpenStack Octavia

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, and thus an authenticated project member who owns a TLS-enabled load balancer can embed a newline and inject arbitrary HAProxy configuration directives. Only deployments using the Amphora provider are affected.

Affected: Ubuntu:22.04:LTS: octavia, Ubuntu:24.04:LTS: octavia, Ubuntu:26.04:LTS: octavia

It was discovered that Octavia did not properly validate TLS cipher string fields in the Amphora provider driver. An authenticated attacker who owns a TLS-enabled load balancer could possibly use this issue to inject arbitrary HAProxy configuration directives. (CVE-2026-94572)

It was discovered that Octavia did not properly validate L7 policy redirect URL fields in the Amphora provider driver. An authenticated attacker who owns a load balancer could possibly use this issue to inject arbitrary HAProxy configuration directives. (CVE-2026-94571)

It was discovered that Octavia incorrectly handled quality of service policy authorization. An authenticated attacker could possibly use this issue to prevent deletion of another project's QoS policy. (CVE-2026-74248)
