CVE-2025-1241Network attack vector

Admin-only data decryption via static initialization vector

Published Apr 21, 2026 · Updated Apr 21, 2026

Inadequate encryption in Fortra GoAnywhere MFT before 7.10.0 allows remote authenticated users with admin rights to decrypt stored data. Encrypted values reuse a static initialization vector, making their ciphertext susceptible to brute-force recovery. Administrative access is required, and the published record limits the impact to confidentiality without identifying which stored values are exposed.
