CVE-2026-33948 jq: Embedded-NUL Truncation in CLI JSON Input Path Causes Prefix-Only Validation of Malformed Input

jq is a command-line JSON processor. Commits before 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b contain a vulnerability where CLI input parsing allows validation bypass via embedded NUL bytes. When reading JSON from files or stdin, jq uses strlen to determine buffer length instead of the actual byte...

CVE-2026-33948

CVE-2026-33948 affects jq, a command-line JSON processor. Before commit 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b, input parsing uses strlen() on data read from files or stdin, causing truncation at the first NUL byte and validating only the prefix as JSON. This enables an attacker to craft input ...
