Unwanted record processing via omitted suppression check
Published Apr 22, 2026 · Updated Apr 22, 2026
Incorrect output filtering in uutils coreutils cut before 0.8.0 allows local users to pass undelimited records through automated pipelines. The -z and empty-delimiter combination enters a specialized newline-delimiter path that omits the -s suppression check and emits the full record plus NUL. Local execution with that exact option combination is required; affected pipelines process data intended for discard, without code execution or disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
