CVE-2026-105570 (GCVE-0-2026-105570)

Vulnerability from nvd – Published: 2026-10-08 18:46 – Updated: 2026-10-08 19:28

Title

Docker Sandboxes OAuth response masking could be bypassed with a case-variant token host

Summary

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 hostname to reach the genuine provider endpoint while bypassing response masking. If a user completed the OAuth flow, the provider's access and refresh tokens could be returned unmasked to the sandbox, exposing host-managed credentials.

Severity

6.7 (Medium)

CVE-2026-105452 (GCVE-0-2026-105452)

Vulnerability from nvd – Published: 2026-10-08 18:49 – Updated: 2026-10-08 19:29

Title

Docker Sandboxes egress proxy could forward unrecognized client credentials to managed hosts

Summary

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 could supply an unrecognized credential in another supported authentication header. For affected upstream services, this could authenticate the request to an attacker-controlled account and expose data included in the request.

Severity

5.9 (Medium)

CVE-2026-101998 (GCVE-0-2026-101998)

Vulnerability from nvd – Published: 2026-10-08 18:47 – Updated: 2026-10-08 19:27

Title

Fail-open response masking in Docker Sandboxes can expose proxy-managed credentials

Summary

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 recover host-managed OAuth access and refresh tokens or a derived Anthropic API key intended to remain outside the sandbox.

Severity

CVE-2026-79994 (GCVE-0-2026-79994)

Vulnerability from nvd – Published: 2026-09-15 20:33 – Updated: 2026-09-16 17:57

Title

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

Summary

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 connect to an arbitrary AF_UNIX socket outside the shared workspace. This can expose data or host-side capabilities provided by the targeted socket.

Severity

8.7 (High)

CVE-2026-77179 (GCVE-0-2026-77179)

Vulnerability from nvd – Published: 2026-09-15 13:32 – Updated: 2026-09-15 21:43

Title

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

Summary

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, potentially achieving host code execution.

Severity

9.4 (Critical)

CVE-2026-17106 (GCVE-0-2026-17106)

Vulnerability from nvd – Published: 2026-08-18 18:35 – Updated: 2026-08-19 03:56

Title

Tar extraction in moby/go-archive can write outside the destination directory via link following

Summary

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 string checks and then performs the filesystem operation on a path that is resolved by the OS, so links introduced by the archive can be followed out of the destination directory. An attacker who controls the contents of an archive can create or overwrite files at arbitrary paths writable by the extracting process.

Severity

7.1 (High)

CVE-2026-18171 (GCVE-0-2026-18171)

Vulnerability from nvd – Published: 2026-08-12 14:47 – Updated: 2026-08-12 17:02

Title

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

Summary

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 code inside the sandbox can derive that path and write to a host directory the operator attached read-only.

Severity

5.7 (Medium)

CVE-2026-12539 (GCVE-0-2026-12539)

Vulnerability from nvd – Published: 2026-06-18 13:51 – Updated: 2026-08-13 13:33

Title

Docker Sandboxes ICMP egress restriction bypass after daemon restart

Summary

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 model treats as untrusted, can therefore defeat the documented ICMP egress block to perform network reconnaissance and exfiltrate data over an ICMP covert channel, regardless of the configured allowlist.

Severity

CVE-2026-12039 (GCVE-0-2026-12039)

Vulnerability from nvd – Published: 2026-06-18 13:48 – Updated: 2026-08-13 13:33

Title

Docker Sandboxes network egress allowlist bypass via unfiltered DNS resolution

Summary

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 the threat model treats as untrusted, can therefore encode data into DNS labels for an attacker-controlled domain and exfiltrate it through a DNS covert channel, bypassing the configured allowlist.

Severity

5.7 (Medium)

CVE-2026-105452 (GCVE-0-2026-105452)

Vulnerability from cvelistv5 – Published: 2026-10-08 18:49 – Updated: 2026-10-08 19:29

Title

Docker Sandboxes egress proxy could forward unrecognized client credentials to managed hosts

Summary

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 could supply an unrecognized credential in another supported authentication header. For affected upstream services, this could authenticate the request to an attacker-controlled account and expose data included in the request.

Severity

5.9 (Medium)

CVE-2026-101998 (GCVE-0-2026-101998)

Vulnerability from cvelistv5 – Published: 2026-10-08 18:47 – Updated: 2026-10-08 19:27

Title

Fail-open response masking in Docker Sandboxes can expose proxy-managed credentials

Summary

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 recover host-managed OAuth access and refresh tokens or a derived Anthropic API key intended to remain outside the sandbox.

Severity

5.9 (Medium)

CVE-2026-105570 (GCVE-0-2026-105570)

Vulnerability from cvelistv5 – Published: 2026-10-08 18:46 – Updated: 2026-10-08 19:28

Title

Docker Sandboxes OAuth response masking could be bypassed with a case-variant token host

Summary

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 hostname to reach the genuine provider endpoint while bypassing response masking. If a user completed the OAuth flow, the provider's access and refresh tokens could be returned unmasked to the sandbox, exposing host-managed credentials.

Severity

6.7 (Medium)

CVE-2026-79994 (GCVE-0-2026-79994)

Vulnerability from cvelistv5 – Published: 2026-09-15 20:33 – Updated: 2026-09-16 17:57

Title

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

Summary

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 connect to an arbitrary AF_UNIX socket outside the shared workspace. This can expose data or host-side capabilities provided by the targeted socket.

Severity

8.7 (High)

CVE-2026-77179 (GCVE-0-2026-77179)

Vulnerability from cvelistv5 – Published: 2026-09-15 13:32 – Updated: 2026-09-15 21:43

Title

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

Summary

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, potentially achieving host code execution.

Severity

9.4 (Critical)

CVE-2026-17106 (GCVE-0-2026-17106)

Vulnerability from cvelistv5 – Published: 2026-08-18 18:35 – Updated: 2026-08-19 03:56

Title

Tar extraction in moby/go-archive can write outside the destination directory via link following

Summary

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 string checks and then performs the filesystem operation on a path that is resolved by the OS, so links introduced by the archive can be followed out of the destination directory. An attacker who controls the contents of an archive can create or overwrite files at arbitrary paths writable by the extracting process.

Severity

7.1 (High)

CVE-2026-18171 (GCVE-0-2026-18171)

Vulnerability from cvelistv5 – Published: 2026-08-12 14:47 – Updated: 2026-08-12 17:02

Title

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

Summary

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 code inside the sandbox can derive that path and write to a host directory the operator attached read-only.

Severity

5.7 (Medium)

CVE-2026-12539 (GCVE-0-2026-12539)

Vulnerability from cvelistv5 – Published: 2026-06-18 13:51 – Updated: 2026-08-13 13:33

Title

Docker Sandboxes ICMP egress restriction bypass after daemon restart

Summary

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 model treats as untrusted, can therefore defeat the documented ICMP egress block to perform network reconnaissance and exfiltrate data over an ICMP covert channel, regardless of the configured allowlist.

Severity

5.1 (Medium)

CVE-2026-12039 (GCVE-0-2026-12039)

Vulnerability from cvelistv5 – Published: 2026-06-18 13:48 – Updated: 2026-08-13 13:33

Title

Docker Sandboxes network egress allowlist bypass via unfiltered DNS resolution

Summary

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 the threat model treats as untrusted, can therefore encode data into DNS labels for an attacker-controlled domain and exfiltrate it through a DNS covert channel, bypassing the configured allowlist.

Severity
