What it is

Scoold is a Q&A and a knowledge sharing platform for teams. Prior to 1.69.0, authenticated users who are not members of a private space can create content in questions belonging to that space because src/main/java/com/erudika/scoold/controllers/QuestionController.java in QuestionController.reply() and src/main/java/com/erudika/scoold/controllers/CommentController.java in CommentController.createAjax() do not apply the canAccessSpace authorization check used by the question read path. With scoold.is_default_space_public set to false and private spaces in use, a user with a valid session and a known or enumerable question identifier can send requests to POST /question/{id} and POST /comment, causing replies and comments to be stored in a thread the user cannot read. This permits unauthorized modification of private discussions and can trigger notifications that reveal the existence or metadata of private activity. This issue is fixed in version 1.69.0.
