Summary
ENC DataVault 7.2.3 and before, and OEM versions, use an encryption algorithm that is vulnerable to data manipulation (without knowledge of the key). This is called ciphertext malleability. There is no data integrity mechanism to detect this manipulation.
Exploit prediction
0.50% chance of exploitation in the next 30 days, higher than 43% of all scored CVEs (FIRST EPSS, 2026-11-08).
