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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":37,"depthScoreParts":{"impact":36.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":220533,"id":"CVE-2026-105570","ts":1792022655364,"field":"cvss","old":null,"new":"6.7"},{"seq":220532,"id":"CVE-2026-105570","ts":1792022655364,"field":"severity","old":"none","new":"medium"}]}
