CVE-2026-13067

tlsCATrusts Role Restriction Not Enforced via PROXY Protocol v2 on Unix Domain Socket PUBLISHED

Description (CNA)

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.
