GHSA-W6XC-G9QJ-VP32 uucore: safe_traversal TOCTOU protection only enabled on Linux

The safetraversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use TOCTOU symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize...

GHSA-H444-6J9X-P8VH mv: symlinks expanded during cross-device move (resource exhaustion / data duplication)

When moving directories across filesystems, uutils mv dereferences symlinks inside the tree, copying their targets as real files/dirs instead of preserving the symlinks. GNU preserves symlinks by default. E.g. a etclink - /etc inside the source becomes a full copy of /etc at the destination...

DEBIAN-CVE-2026-58403

Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo's virtual filesystem is designed so that files under a mount cannot reach outside the mount tree, but a regression caused RootMappingFs.statRoot to call Stat, which follows symlinks, instead of Lstat, so a direct os.ReadFile...

GHSA-7CR3-H577-G38J rm: --preserve-root bypassed via a symlink to / (string check instead of dev/inode)

The --preserve-root check uses a path-string test path.hasroot && path.parent.isnone rather than comparing device/inode. A symlink to / e.g. /tmp/rootlink - / has a parent component, so it passes the check. GNU caches /'s dev/inode at startup and compares every traversed directory against it...

GHSA-GWM6-Q8CH-HCFR install -D: symlink race in directory creation allows arbitrary file overwrite

The -D path runs fs::createdirall on a pathname then later opens the destination via path-based File::create/fs::copy, neither anchored to a directory fd. Between the two, an attacker can replace a path component with a symlink, redirecting the write. Impact: an attacker with concurrent write...

GHSA-239G-2685-54X3 install: TOCTOU symlink race (unlink-then-create without O_EXCL) allows arbitrary file overwrite

copyfile in install/src/install.rs removes the destination then recreates it by pathname via File::create / fs::copy without OEXCL/createnew. Between the unlink and the recreate, a local attacker with write access to the destination directory can drop in a symlink and redirect the write. Impact:...

CVE-2026-50135

Summary: Hugo up to v0.161.1 is affected by a symlink confinement bypass in the virtual filesystem used by Hugo’s resources.Get. Root cause: A regression in RootMappingFs.statRoot caused it to call Stat (which follows symlinks) instead of Lstat, allowing a symlink inside a mounted directory (e.g....
