{"id":"DEBIAN-CVE-2026-94572","details":"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.","modified":"2026-09-25T08:47:23.002388520Z","published":"2026-09-21T21:17:22.150Z","upstream":["CVE-2026-94572"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-94572"}],"affected":[{"package":{"name":"octavia","ecosystem":"Debian:12","purl":"pkg:deb/debian/octavia?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.0.0-2","12.0.0-1","12.0.0-2","12.0.0-3","12.0.0-4","12.0.0~rc1-1","12.0.0~rc2-1","13.0.0-1","13.0.0-2","13.0.0~rc1-1","14.0.0-1","14.0.0-2","14.0.0-3","14.0.0-4","14.0.0~rc1-1","15.0.0-1","15.0.0-2","15.0.0-3","15.0.0~rc1-1","15.0.0~rc1-2","15.0.0~rc1-3","16.0.0-1","16.0.0-2","16.0.0-3","16.0.0~rc1-1","16.0.0~rc1-2","17.0.0-1","17.0.0-2","17.0.0-3","17.0.0-4","17.0.0-5","17.0.0~rc1-1","17.0.0~rc2-1","17.0.0~rc2-2","17.0.0~rc2-3","18.0.0-1","18.0.0-2","18.0.0-3","18.0.0-4","18.0.0~rc1-1","18.0.0~rc1-2","19.0.0~rc1-1","19.0.0~rc1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-94572.json"}},{"package":{"name":"octavia","ecosystem":"Debian:13","purl":"pkg:deb/debian/octavia?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["16.0.0-2","16.0.0-3","17.0.0-1","17.0.0-2","17.0.0-3","17.0.0-4","17.0.0-5","17.0.0~rc1-1","17.0.0~rc2-1","17.0.0~rc2-2","17.0.0~rc2-3","18.0.0-1","18.0.0-2","18.0.0-3","18.0.0-4","18.0.0~rc1-1","18.0.0~rc1-2","19.0.0~rc1-1","19.0.0~rc1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-94572.json"}},{"package":{"name":"octavia","ecosystem":"Debian:14","purl":"pkg:deb/debian/octavia?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.0.0-4"}]}],"versions":["16.0.0-2","16.0.0-3","17.0.0-1","17.0.0-2","17.0.0-3","17.0.0-4","17.0.0-5","17.0.0~rc1-1","17.0.0~rc2-1","17.0.0~rc2-2","17.0.0~rc2-3","18.0.0-1","18.0.0-2","18.0.0-3","18.0.0~rc1-1","18.0.0~rc1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-94572.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
