Summary

The homestay-backend 0.0.1-SNAPSHOT application contains an IDOR vulnerability in ChatServiceImpl. An authenticated user can view conversations, read and send messages, and mark messages as read for arbitrary conversation IDs because the service does not verify that the caller is a conversation participant.

Risk Assessment

An authenticated user can access other users' private conversations, resulting in a confidentiality breach that may lead to data leakage and privacy violations.

Recommendation

Implement authorization checks verifying that the user is a participant of the conversation before granting access to or modifying its content. Update the application to a patched version.
