CVE-2021-36751 is a medium-severity flaw (CVSS 4.2) affecting datavault. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
