Vulnerability from github – Published: 2026-10-08 21:33 – Updated: 2026-10-08 21:33

Details

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)
