CVE-2026-94572

Status: Awaiting AnalysisCritical (9.4)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Un usuario autenticado con privilegios en OpenStack Octavia (T1210: explotación de servicio remoto) inyecta directivas HAProxy maliciosas mediante campos tls_ciphers no validados, logrando ejecución de comandos en la instancia Amphora (T1059.007) y manipulación de configuración (T1565.002).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
