Detailsinfo

A vulnerability was found in Qwibit NanoClaw (affected version not known). It has been declared as critical. Affected by this vulnerability is some unknown functionality of the component Message Handler. The manipulation of the argument messages_out.id/content.files 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 confidentiality, integrity, and availability. The summary by CVE is:

NanoClaw version 1.2.0 and prior contains a host/container filesystem boundary vulnerability in outbound attachment handling and outbox cleanup that allows a compromised or prompt-injected container to read files outside the intended outbox directory by supplying crafted messages_out.id and content.files values or creating symlinked outbox files. Attackers can exploit this vulnerability to trigger host-side reads of arbitrary files and in some cases achieve recursive deletion of paths outside the intended cleanup target.

The weakness was presented by Chia Min Jun Lennon. The advisory is shared at github.com. This vulnerability is known as CVE-2026-7875 since 05/05/2026. The exploitation appears to be easy.
