CVE-2026-94572 (GCVE-0-2026-94572)

Vulnerability from cvelistv5 – Published: 2026-09-21 20:13 – Updated: 2026-09-21 20:13
VLAI
Summary
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.
