CVE-2026-101998: Fail-open response masking in Docker Sandboxes can expose proxy-managed credentials
Medium · CVSS 5.9 (CVSS 4.0)EPSS 0.16%, 5th percentilePublished Updated Assigner: Docker
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.
