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 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....

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...

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-...

Mapping the Exploitation Surface: A 10,000-Trial Taxonomy of What Makes LLM Agents Exploit Vulnerabilities

LLM agents with tool access can discover and exploit security vulnerabilities. This is known. What is not known is which features of a system prompt trigger this behaviour, and which do not. We present a systematic taxonomy based on approximately 10,000 trials across seven models, 37 prompt...
