What the CVE records say

CVE-2026-43895 — jq is a command-line JSON processor. In 1.8.1 and earlier, jq accepts embedded NUL bytes in import paths at the jq-language level, but later resolves those paths through C string operations during module and data-file lookup. This creates a mismatch between the logical import string that policy or audit code may validate and the on-disk path that jq actually opens.

Impact

Successful exploitation of this vulnerability could lead to disclosure of sensitive information, addition or modification of data.

Affected products

Cloud Volumes ONTAP Mediator
NetApp SolidFire & HCI Management Node
NetApp SolidFire & HCI Storage Node (Element Software)
