The vulnerability affects BookWyrm versions up to 0.9.1, where the status edit endpoint does not properly validate user visibility permissions. This allows authenticated attackers to exploit sequential status IDs to access followers-only and direct-message reviews, compromising the privacy of sensitive user content. Organizations using this software should prioritize patching to mitigate potential data exposure risks.

Original NVD Description

BookWyrm through 0.9.1 fails to validate user visibility permissions in the status edit endpoint, allowing authenticated attackers to read followers-only and direct-message reviews by enumerating sequential status IDs. Attackers can access the raw content of restricted statuses through the edit view, bypassing the privacy protections documented for these message types.
