CyberRota Analysis

AI-Generated

The OAuth Ruby wrapper versions 0.5.5 to 1.1.5 are vulnerable due to improper handling of redirect responses, allowing attackers to manipulate consumer configurations and expose sensitive OAuth request metadata, including the Authorization header, to unintended cross-origin hosts. This vulnerability poses a significant risk to applications relying on OAuth for authentication and authorization. Developers and security teams using affected versions should prioritize upgrading to version 1.1.6 to mitigate potential data exposure risks.

Original NVD Description

OAuth is a Ruby wrapper for the OAuth 1.0 and 1.0a protocols, providing clients and servers. From 0.5.5 to 1.1.5, OAuth::Consumer#token_request parses the raw Location header of a 300 to 399 redirect returned by the OAuth server and follows the redirect recursively, which can mutate the consumer's configuration and expose signed OAuth request metadata, including the Authorization header, to a cross-origin host. This issue is fixed in version 1.1.6.
