CVE-2026-43895
jq: Embedded NUL in jq import paths causes local redaction-policy bypass and preserves sensitive fields in published artifacts
4.4CVSSMEDIUM
Description
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.
