Para is a multitenant backend server/framework for object persistence and retrieval. A vulnerability that exists in versions prior to 1.50.8 in "FacebookAuthFilter.java" results in a full request URL being logged during a failed request to a Facebook user profile. The log includes the user's access token in plain text. Since WARN-level logs are often retained in production and accessible to operators or log aggregation systems, this poses a risk of token exposure. Version 1.50.8 fixes the issue.
