Detailsinfo

A vulnerability was found in Uutils coreutils (affected version unknown). It has been declared as critical. Affected by this vulnerability is an unknown functionality of the component Rm Utility. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed by Zellic. The advisory is shared at github.com. This vulnerability is known as CVE-2026-35363 since 04/02/2026. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue.
