CVE-2026-43895 | BDVDB-2026-332183 Detail

jqlangjq

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.

Impact#

Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact none. Attack vector: local.

Weaknesses#

  • CWE-20 Improper Input Validation
  • CWE-158 Improper Neutralization of Null Byte or NUL Character
