Kerentanan Improper Neutralization of Null Byte or NUL Character pada jqlang jq. Skor CVSS 3.1 5.5 (Medium) menurut github.com.

Deskripsi (NVD)

jq is a command-line JSON processor. In 1.8.1 and earlier, Top-level jq programs loaded from a file with -f are truncated at the first embedded NUL byte on current upstream HEAD. A crafted filter file such as . followed by \x00 and arbitrary suffix compiles and executes as only the prefix before the NUL. This leaves jq with a post-CVE-2026-33948 prefix/full-buffer mismatch on the compilation path even though the JSON parser path has already been fixed.
