CyberRota Analysis
AI-GeneratedThe canto-saas-api PHP library prior to version 3.0.0 is vulnerable due to improper handling of sensitive credentials, which are exposed in plaintext within URL query strings and application logs during token requests. This flaw allows an attacker with access to logs or telemetry data to obtain Canto credentials, potentially leading to unauthorized access to tenant resources. Organizations using affected versions should prioritize upgrading to version 3.0.0 to mitigate the risk of credential exposure.

Original NVD Description
canto-saas-api is a PHP library for interacting with the Canto SaaS API. Prior to version 3.0.0, OAuth2Request::getQueryParams() places app_id, app_secret, refresh_token, and code in the URL query string of token POST requests, allowing access logs, proxy logs, and APM traces to persist the credentials in plaintext. When a token request fails, OAuth2::obtainAccessToken() also passes the credential-bearing Guzzle request URI into AuthorizationFailedException, so application logs and error trackers can record the same secrets. An attacker with access to affected telemetry can obtain Canto credentials and use them to request access tokens for the tenant. This issue is fixed in version 3.0.0.
