CVE-2026-81101Network attack vectorHinoki check available

Credential disclosure via unvalidated configured endpoint

Published Aug 27, 2026 · Updated Aug 27, 2026

Information disclosure in Airtable MCP CLI before 0.2.5 allows remote attackers to obtain a personal access token after user interaction. ConfigureCommand.execute stores the endpoint option without createSafeUrl validation, and the MCP connect path sends the saved token as a bearer credential to that endpoint. Exploitation requires persuading a user to configure an attacker-controlled endpoint; later CLI requests disclose the token to that server.
