{"id":"GHSA-pmfc-4wjj-gmhx","summary":"cut: -s ignored in -z -d '' newline-delimiter mode","details":"`cut` routes `-z -d ''` through a special newline-delimiter path that ignores the `-s` only-delimited flag, emitting whole undelimited records (plus NUL) that should be suppressed. Pipelines relying on `cut -s` to drop undelimited records process data that should be filtered.\n```\nprintf 'abc' | cut -z -d '' -s -f 1 | od -An -tx1   # GNU: no output ; uutils: 61 62 63 00\n```\n\n---\n_Zellic private finding (zellic-ext/coreutils-private PR #102).
