Celah bernomor CVE-2026-104286 itu memiliki skor CVSS 9,8.<\/p>\n<p>Kerentanan tersebut memengaruhi beberapa versi platform keamanan email Fortinet. Perusahaan menyebut penyebabnya merupakan gabungan path traversal dan penanganan karakter null yang tidak tepat pada antarmuka web FortiMail. Penyerang tanpa autentikasi dapat mengirim permintaan HTTP atau HTTPS yang dirancang khusus untuk menulis file arbitrer ke sistem. Penulisan file di lokasi tertentu dapat memungkinkan eksekusi kode atau perintah pada perangkat.<\/p>\n<p><strong>Baca juga<\/strong>: <a href=\"https:\/\/vlobs.com\/blog\/pengiriman-tesla-kuartal-iii\">Tesla Catat 486.532 Pengiriman Kendaraan pada Kuartal III<\/a><\/p>\n<p>Versi yang terdampak adalah FortiMail 8.0.0 hingga 8.0.1, 7.6.0 hingga 7.6.6, 7.4.0 hingga 7.4.8, serta 7.2.0 hingga 7.2.9.

Perusahaan merekomendasikan agar Identity Based Encryption dinonaktifkan jika tidak diperlukan.<\/p>\n<p>Jika fitur tersebut tidak dapat dinonaktifkan, Fortinet menyarankan agar antarmuka pengelolaan FortiMail tidak dapat dijangkau dari internet dan akses dibatasi ke jaringan privat tepercaya. Administrator juga diminta memeriksa kemungkinan kompromi, sebab penerapan solusi sementara tidak menghapus file atau mekanisme persistensi yang mungkin telah ditanam penyerang.<\/p>\n<p><strong>Baca juga<\/strong>: <a href=\"https:\/\/vlobs.com\/blog\/kelompok-ransomware-killsec\">Polisi Sita Infrastruktur KillSec, Tiga Orang Ditangkap Sementara<\/a><\/p>\n<p>CISA telah memasukkan CVE-2026-104286 ke katalog Known Exploited Vulnerabilities.
