Base vector

AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions jq versions 1.8.1 and earlier

Description jq accepts embedded NUL bytes in import paths at the jq-language level, but subsequently resolves those paths using C string operations during module and data-file lookup. This results in a mismatch between the logical import string validated by policy or audit code and the actual on-disk path that the software opens.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
