CVE-2026-77179

CVE-2026-77179 is a CRITICAL (CVSS 4.0: 9.4) vulnerability in Docker Sandboxes on macOS. The virtio-fs host server improperly follows symlinks when reopening an unlinked file from a stored path, allowing a malicious guest to replace a parent directory with a symlink, escape the shared workspace, ...

EUVD-2026-78467

On macOS, the virtio-fs host server used by Docker Sandboxes improperly follows symlinks when reopening an unlinked file from a stored path. A malicious guest can replace a parent directory with a symlink, escape the shared workspace, and read or modify arbitrary host files as the VMM user,...

CVE-2026-77179 Docker Sandboxes guest can write arbitrary macOS host files via a symlink in the virtio-fs stored-path fallback

On macOS, the virtio-fs host server used by Docker Sandboxes improperly follows symlinks when reopening an unlinked file from a stored path. A malicious guest can replace a parent directory with a symlink, escape the shared workspace, and read or modify arbitrary host files as the VMM user,...

CVE-2026-79994: Time-of-check Time-of-use (TOCTOU) Race Condition

The guest-to-host Unix-domain socket relay in Docker Sandboxes validates that a socket path is inside an authorized workspace, but later reconnects using the pathname. A malicious guest can replace an intermediate directory with a symlink between validation and connection, causing the host to...

CVE-2026-77179: Improper Link Resolution Before File Access

On macOS, the virtio-fs host server used by Docker Sandboxes improperly follows symlinks when reopening an unlinked file from a stored path. A malicious guest can replace a parent directory with a symlink, escape the shared workspace, and read or modify arbitrary host files as the VMM user,...

CVE-2026-18171

Docker Sandboxes sbx applies the read-only intent of a runtime host mount to the in-guest container bind only: the underlying virtio-fs host-edge grant is added to the sandbox's policy-share allowlist with no access mode. The directory stays writable at its shared-export path, so unprivileged cod...

CVE-2026-12039

Docker Sandboxes sbx enforces an HTTP/S-only egress allowlist but does not apply it to DNS resolution: the per-network embedded DNS server forwards any queried name to the host resolver whenever the network is internet-connected, without consulting the policy. A workload inside a sandbox, which t...

CVE-2026-12539

Docker Sandboxes (sbx) ICMP egress restriction can be bypassed after daemon restart. The issue arises because the authorizer is applied only at network creation and is not re-applied to networks rebuilt from disk on restart, allowing a restart-surviving sandbox to forward ICMP to arbitrary hosts....

CVE-2026-12539

Docker Sandboxes sbx blocks ICMP egress with an authorizer applied only at network-creation time, and does not re-apply it to networks rebuilt from disk when the Docker daemon restarts, so a restart-surviving sandbox forwards ICMP to arbitrary hosts. A workload inside a sandbox, which the threat...
