Vulnerability from github – Published: 2026-07-06 20:20 – Updated: 2026-07-06 20:20

Summary

rm: 'rm -rf ./' (and ./// variants) silently deletes current directory contents, bypassing dot protection

Details

rm -rf . is correctly refused, but clean_trailing_slashes normalizes ./// to ./ while path_is_current_or_parent_directory only matches ./.. (and /.//..), not ./ or ../. So rm -rf ./ recursively deletes the directory's contents and then prints a misleading cannot remove './': Invalid input.

Impact: all files/subdirectories in the current directory are silently deleted; the misleading error makes users miss the recovery window. Recommendation: handle trailing-slash variants in path_is_current_or_parent_directory.

Remediation: Acknowledged by Canonical; fixed in commit d0e5af23.

Reported by Zellic in the uutils coreutils Program Security Assessment (prepared for Canonical, Jan 20 2026), audited commit 3a07ffc5a9bd4c283e75afa548ba1f1957bad242. Finding 3.60. Credit: Zellic.

CVE-2026-35363 (GCVE-0-2026-35363)

Vulnerability from cvelistv5 – Published: 2026-04-22 16:08 – Updated: 2026-04-22 17:24

Title

uutils coreutils rm Safeguard Bypass via Improper Path Normalization

Summary

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.
