CVE-2026-105570 | BDVDB-2026-384694 Detail

Description#

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.
