CVE-2026-35363 — Vulnerability in uu_rm — CVE Details

MEDIUM

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

Published July 6, 2026Updated July 6, 2026Source: osv

Summary

`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._ _Upstream tracking issue: https://github.com/uutils/coreutils/issues/9749 · CVE-2026-35363_
