In versions 0.7.0 and below, due to incorrect handling of the mail.Address values when a sender- or recipient address is passed to the corresponding MAIL FROM or RCPT TO commands of the SMTP client, there is a possibility of wrong address routing or even ESMTP parameter smuggling. For successful exploitation, it is required that the user's code allows for arbitrary mail address input (i. e. through a web form or similar). If only static mail addresses are used (i. e. in a config file) and the mail addresses in use do not consist of quoted local parts, this should not affect users. This issue is fixed in version 0.7.1","state":0,"publishedAt":"2025-09-29T22:21:02.484+00:00","modifiedAt":"2025-09-30T14:44:35.194+00:00","affected":[{"ecosystem":"Vendor product","name":"go-mail","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wneessen\",\n                    \"product\": \"go-mail\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.7.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.2,"severity":"HIGH"}],"references":["https://github.com/wneessen/go-mail/security/advisories/GHSA-wpwj-69cm-q9c5","https://github.com/wneessen/go-mail/issues/495","https://github.com/wneessen/go-mail/pull/496","https://github.com/wneessen/go-mail/commit/42e92cfe027be04aff72921adb0f72f11d517479"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-59937","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-59937","identifiers":["CVE-2025-59937"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
