CVE-2026-43895: Jqlang Jq

Medium severity, CVSS 4.4. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Jqlang Jq: up to and including 1.8.1
