NVD description
An improper access control vulnerability in danny-avila/librechat versions prior to 0.7.6 allows authenticated users to delete other users' prompts via the groupid parameter. This issue occurs because the endpoint does not verify whether the provided prompt ID belongs to the current user.
What to do
- Upgrade LibreChat to
0.7.6or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
