{"id":"BIT-mongodb-2026-13067","summary":"tlsCATrusts Role Restriction Not Enforced via PROXY Protocol v2 on Unix Domain Socket","details":"When PROXY protocol v2 is used on the Unix domain socket path, roles derived from X.509 client certificates may not be validated against the configured tlsCATrusts allow-list. This can result in unintended role assignments following MONGODB-X509 authentication. Affected scenarios require local access to the proxy Unix domain socket and a valid X.509 certificate issued by a trusted certificate authority.","aliases":["CVE-2026-13067"],"modified":"2026-09-08T08:48:14.379189124Z","published":"2026-08-17T05:49:36.874Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:mongodb:mongodb:*:*:*:*:-:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://jira.mongodb.org/browse/SERVER-128387"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13067"}],"affected":[{"package":{"name":"mongodb","ecosystem":"Bitnami","purl":"pkg:bitnami/mongodb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.0.0"},{"fixed":"8.0.28"},{"introduced":"8.3.0"},{"fixed":"8.3.7"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mongodb/BIT-mongodb-2026-13067.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/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"}]}],"schema_version":"1.9.0"}
