CVE-2026-13067

MEDIUM

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

Title source: cna

Description

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.
