CyberRota Analysis
AI-GeneratedThe vulnerability affects Logto's Account API, allowing an attacker with a same-user access token to retrieve sensitive social or enterprise SSO provider access tokens without proper scope validation. This can lead to unauthorized access to user accounts and data, enabling exploitation by low-trust applications against upstream APIs. Organizations using versions 1.31.0 to 1.42.0 should prioritize upgrading to version 1.42.0 to mitigate this risk.

Original NVD Description
Logto is the modern, open-source auth infrastructure for SaaS and AI apps. From 1.31.0 until 1.42.0, the Account API handlers in packages/core/src/routes/account/third-party-tokens.ts allow a caller holding a same-user access token with only the openid scope to retrieve stored social or enterprise SSO provider access tokens through GET /api/my-account/identities/{target}/access-token or GET /api/my-account/sso-identities/{connectorId}/access-token. The handlers authenticate the user but do not require the identities scope that protects neighboring identity-detail operations, bypassing the intended Account API consent boundary. Exploitation requires federated token-set storage to be enabled and the affected user to have authenticated through a supported connector. A low-trust application can use the disclosed provider token against upstream APIs within that token's granted scopes. This issue is fixed in version 1.42.0.
