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...

CVE-2026-12539 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 workload inside a sandbox, which the threat...

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....

EUVD-2026-37892

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-2026-12039

Docker Sandboxes (sbx) expose a DNS resolution bypass: the per-network embedded DNS server forwards queries to the host resolver when the network is internet-connected, ignoring the HTTP/S egress allowlist. This enables a workload treated as untrusted to encode data in DNS labels for an attacker-...

CVE-2026-12039 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 policy. A workload inside a sandbox, which t...

Arbitrary Argument Injection

Overview Affected versions of this package are vulnerable to Arbitrary Argument Injection via the YAML unmarshalling process of the io.docker.server.metadata OCI image label into the catalog.Server struct. An attacker can execute arbitrary code as root on the host system by crafting a malicious O...

GHSA-R2XF-7JW5-PJG6 Docker MCP Gateway: Argument injection via OCI image label YAML

Summary A maliciously crafted OCI image label can inject arbitrary arguments into the docker run command line constructed by the MCP Gateway. An attacker who controls an image that the victim references via docker://, or that the victim's catalog pulls a snapshot from, can mount the host...

PT-2026-50674

Name of the Vulnerable Software and Affected Versions Docker Sandboxes sbx affected versions not specified Description Docker Sandboxes sbx implements an egress allowlist restricted to HTTP/S traffic but fails to apply this restriction to DNS resolution. The embedded DNS server for each network...

PT-2026-50746

Name of the Vulnerable Software and Affected Versions Docker MCP Plugin affected versions not specified Description A flaw in the OCI image label parsing allows an attacker to inject arbitrary arguments into the docker run command line. This occurs because the io.docker.server.metadata label is...

PT-2026-56003

Name of the Vulnerable Software and Affected Versions Crawl4AI versions prior to 0.9.0 Description The Docker API server allows the browser config.extra args parameter to be passed directly into Chromium launch arguments. Because the Docker API is unauthenticated by default, an attacker can injec...

Name of the Vulnerable Software and Affected Versions Docker Sandboxes affected versions not specified Description Docker Sandboxes sbx fail to re-apply the ICMP egress authorizer to networks rebuilt from disk after a Docker daemon restart. This allows a restart-surviving sandbox to forward ICMP...

CVE-2026-12566

The dockerpull module uses the realm parameter from a Docker registry's WWW-Authenticate response header as the authentication endpoint without validation. An attacker in a man-in-the-middle position between bbot and a Docker registry could modify this header to redirect the authentication reques...
