{"id":"CVE-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.","modified":"2026-08-07T03:46:13.377032051Z","published":"2026-07-22T19:16:38.192Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/13xxx/CVE-2026-13067.json","unresolved_ranges":[{"extracted_events":[{"introduced":"8.0"},{"fixed":"8.0.28"},{"introduced":"8.3.0"},{"fixed":"8.3.7"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"mongodb","cwe_ids":["CWE-863"]},"references":[{"type":"WEB","url":"https://jira.mongodb.org/browse/SERVER-128387"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/13xxx/CVE-2026-13067.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13067"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mongodb/mongo","events":[{"introduced":"b41cda4fe697dce6fd9b83b3805362ccc02fbeb3"},{"fixed":"dc5344b376fdfab0fe5b2982f125c056ab0abcd8"},{"introduced":"0f29b043a58fdd251ce0a0b32754b8459613c933"},{"fixed":"527067edda13efcac3d257b3cdb1c510c57b3c6e"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:mongodb:mongodb:*:*:*:*:-:*:*:*","extracted_events":[{"introduced":"8.0.0"},{"fixed":"8.0.28"},{"introduced":"8.3.0"},{"fixed":"8.3.7"}]}}],"versions":["r8.0.24","r8.3.3","r8.3.0","r8.0.17-alpha0","r8.0.16-rc1","r8.0.16","r8.0.16-rc0","r8.0.14-rc1","r8.0.14","r8.0.14-rc0","r8.0.13-rc2","r8.0.13","r8.0.13-rc1","r8.0.13-rc0","r8.0.12-rc0","r8.0.12","r8.0.10-rc0","r8.0.10","r8.0.6","r8.0.5-rc2","r8.0.5","r8.0.5-rc1","r8.0.5-rc0","r8.0.4-rc0","r8.0.4","r8.0.3","r8.0.2","r8.0.1-rc0","r8.0.1","r8.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-13067.json"}}],"schema_version":"1.8.0","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"}]}
