Patch availableThere exists an auth bypass in Google Quickshare where an attacker can upload an unknown file type to a victim. The root cause of the vulnerability lies in the fact that when a Payload Transfer frame of type FILE is sent to Quick Share, the file that is contained in this frame is written to disk in the Downloads folder. Quickshare normally deletes unkown files, however an attacker can send two Payload transfer frames of type FILE and the same payload ID. The deletion logic will only delete the first file and not the second. We recommend upgrading past commit 5d8b9156e0c339d82d3dab0849187e8819ad92c0 or Quick Share Windows v1.0.2002.2

The upload path does not sufficiently restrict the type, name, location or later execution of attacker-supplied files.
An attacker operating through an adjacent network may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-434: Unrestricted Upload of File with Dangerous Type. The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
