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.

Jq 1.8.1 and earlier truncate filter files at the first embedded NUL byte when loaded with -f, causing only the prefix before the NUL to execute. A crafted filter file containing a NUL byte and arbitrary suffix allows an attacker to inject malicious code that compiles and runs silently, bypassing intended filter logic and potentially modifying JSON output in undetected ways. …
