CVE-2026-43895

jq is a command-line JSON processor.

Published May 11, 2026 · updated Jun 17, 2026 · jqlang jq

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.
