The vulnerability allows authenticated attackers to bypass authentication mechanisms in Mastra versions up to 1.63.0 by omitting the mapUserToResourceId callback from configuration, enabling them to enumerate threads and access sensitive conversation history and metadata of other users. Organizations using this software should prioritize patching or reconfiguring their systems to mitigate the risk of unauthorized data exposure. This issue is particularly relevant for environments where sensitive information is handled and user privacy is a concern.
