CVE-2026-35343: Uutils Coreutils

Low severity, CVSS 3.3. EPSS: 0.1% chance of exploitation in the next 30 days.

The cut utility in uutils coreutils incorrectly handles the -s (only-delimited) option when a newline character is specified as the delimiter. The implementation fails to verify the only_delimited flag in the cut_fields_newline_char_delim function, causing the utility to print non-delimited lines that should have been suppressed. This can lead to unexpected data being passed to downstream scripts that rely on strict output filtering.

Affected products

• Uutils Coreutils: before 0.7.0 (fixed in 0.7.0)
