Docker Sandboxes host Git executes repository-controlled programs
Docker Sandboxes versions 0.31.0 before 0.50.0 do not neutralize repository-controlled Git configuration when running certain host-side Git commands. An attacker who can modify a host repository's Git configuration, for example through a direct-mode sandbox w…

Docker Sandboxes sbx cp follows workspace symlinks outside the authorized host directory
Docker Sandboxes sbx cp does not safely confine host-side paths to a shared workspace. A malicious sandbox can create or replace a workspace symlink so that a later user-initiated copy reads a host file outside the workspace into the sandbox or writes sandbox…

Docker Sandboxes egress proxy could forward unrecognized client credentials to managed hosts
Docker Sandboxes could forward a client-supplied credential alongside a credential injected by the host egress proxy. The proxy removed alternate credentials only when their values matched known sentinel values, so untrusted code in an authorized sandbox coul…

Medium 5.9
Fail-open response masking in Docker Sandboxes can expose proxy-managed credentials
Docker Sandboxes could fail open while masking credentials in protected proxy responses. When a response-body read returned data together with an error, affected handlers could forward unmasked bytes. Code inside an authorized sandbox could use this to recove…

Medium 6.7
Docker Sandboxes OAuth response masking could be bypassed with a case-variant token host
Docker Sandboxes compared OAuth token-endpoint hostnames case-sensitively when deciding whether to mask managed credential responses, while request routing treated DNS hostnames case-insensitively. Untrusted code inside a sandbox could use a case-variant host…

High 8.7
Docker Sandboxes UDS forwarder can reach arbitrary host Unix sockets through a symlink race
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 a…

Critical 9.4CVE-2026-77179 Public exploit
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 arbit…

High 7.1CVE-2026-17106 Public exploit
Tar extraction in moby/go-archive can write outside the destination directory via link following
The tar extraction routines in moby/go-archive (Unpack, UnpackLayer, Untar/UntarUncompressed, and the ApplyLayer helpers) do not confine filesystem operations to the destination directory. The extractor decides where each archive entry lands using lexical str…

Docker Sandboxes read-only runtime mount writable through its shared-export alias
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…

Medium 5.1
Docker Sandboxes ICMP egress restriction bypass after daemon restart
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 work…

Medium 5.7
Docker Sandboxes network egress allowlist bypass via unfiltered DNS resolution
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 poli…
