CVE-2026-35363

Description

A vulnerability in the rm utility of uutils coreutils allows the bypass of safeguard mechanisms intended to protect the current directory. While the utility correctly refuses to delete . or .., it fails to recognize equivalent paths with trailing slashes, such as ./ or .///. An accidental or malicious execution of rm -rf ./ results in the silent recursive deletion of all contents within the current directory. The command further obscures the data loss by reporting a misleading 'Invalid input' error, which may cause users to miss the critical window for data recovery.
