CVE-2026-35338: Improper Limitation of a Pathname to a Restricted Directory

A vulnerability in the chmod utility of uutils coreutils allows users to bypass the --preserve-root safety mechanism. The implementation only validates if the target path is literally / and does not canonicalize the path. An attacker or accidental user can use path variants such as /../ or symbol...

CVE-2026-35343: Always-Incorrect Control Flow Implementation

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 onlydelimited flag in the cutfieldsnewlinechardelim function, causing the utility to print non-delimited lines that...

CVE-2026-35372: UNIX Symbolic Link (Symlink) Following

A logic error in the ln utility of uutils coreutils allows the utility to dereference a symbolic link target even when the --no-dereference or -n flag is explicitly provided. The implementation previously only honored the "no-dereference" intent if the --force overwrite mode was also enabled. Thi...

CVE-2026-35380: Improper Input Validation

A logic error in the cut utility of uutils coreutils causes the program to incorrectly interpret the literal two-byte string '' two single quotes as an empty delimiter. The implementation mistakenly maps this string to the NUL character for both the -d delimiter and --output-delimiter options. Th...

uutils coreutils security vulnerabilities

uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. There is a security vulnerability in uutils coreutils, which stems from the cut utility’s improper handling of the -s option when a specified newline character is used as the delimiter. This issue...

CVE-2026-35371: User Interface (UI) Misrepresentation of Critical Information

The id utility in uutils coreutils exhibits incorrect behavior in its "pretty print" output when the real UID and effective UID differ. The implementation incorrectly uses the effective GID instead of the effective UID when performing a name lookup for the effective user. This results in misleadi...

CVE-2026-35373: Improper Handling of Unicode Encoding

A logic error in the ln utility of uutils coreutils causes the program to reject source paths containing non-UTF-8 filename bytes when using target-directory forms e.g., ln SOURCE... DIRECTORY. While GNU ln treats filenames as raw bytes and creates the links correctly, the uutils implementation...

uutils coreutils: Input validation error vulnerability

uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. uutils coreutils has a vulnerability related to input validation. This vulnerability arises from the comm utility consuming data from unconventional file inputs before performing comparison operations...

CVE-2026-35350: Improper Preservation of Permissions

The cp utility in uutils coreutils fails to properly handle setuid and setgid bits when ownership preservation fails. When copying with the -p preserve flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining origin...
