CVE-2026-101998 | BDVDB-2026-384648 Detail

DockerDocker Sandboxes

Description#

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.

Impact#

Per CVSS v4.0: confidentiality impact high, integrity impact none, availability impact none. Attack vector: adjacent.
