CVE-2026-107935

CriticalCVSS 9.3
Published: Translated: NVD NIST

Summary

A path traversal vulnerability was found in gvproxy, the network forwarder provided by the gvisor-tap-vsock package. The unauthenticated /services/forwarder/expose endpoint does not validate the caller-supplied socket path, allowing an attacker to delete arbitrary files on the host system.

Risk Assessment

An attacker could delete critical system files, leading to system failure or data loss.

Recommendation

Update the gvisor-tap-vsock package to a version containing the fix. If an update is not possible, restrict access to the /services/forwarder/expose endpoint.
