Package Type Update Change
go (source) toolchain patch 1.26.4 → 1.26.5

Root escape via symlink plus trailing slash in os

CVE-2026-39822 / GO-2026-4970

More information

Details

On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /.

For example, 'root.Open("symlink/")' will open "symlink" even when "symlink" is a symbolic link pointing outside of the root.
