CVE-2026-43895

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 o...

CVE-2026-43895

jq versions 1.8.1 and earlier are affected: embedded NUL bytes in import paths at the jq-language level can be resolved differently during module/data-file lookup, creating a mismatch between the logical import string and the on-disk path opened. This mismatch can enable a local redaction-policy ...

CVE-2026-41256 jq: Embedded NUL truncates top-level jq programs loaded with -f

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...

CVE-2026-23863

An attachment spoofing issue in WhatsApp for Windows prior to v2.3000.1032164386.258709 could have allowed maliciously formatted documents with embedded NUL bytes in the filename to be shown in the application as one type of file but run as an executable when opened. We have not seen evidence of...

CVE-2026-23863

CVE-2026-23863 affects WhatsApp for Windows prior to version 2.3000.1032164386.258709. The issue is an attachment spoofing flaw where documents with embedded NUL bytes in the filename could be displayed as one file type but executed when opened. Root cause is improper handling of specially crafte...

SUSE CVE-2026-33948

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

A flaw was found in jq, a command-line JSON processor. This vulnerability allows a remote attacker to bypass input validation by crafting malicious JSON input containing embedded null NUL bytes. Due to incorrect handling of input buffer lengths, jq truncates the input at the first NUL byte,...
