An Insecure Direct Object Reference (IDOR) vulnerability exists in the lunary-ai/lunary repository, version 0.3.0, within the project update endpoint. The vulnerability allows authenticated users to modify the name of any project within the system without proper authorization checks, by directly referencing the projects ID in the PATCH request to the /v1/projects/:projectId endpoint. This issue arises because the endpoint does not verify if the provided project ID belongs to the currently authenticated user, enabling unauthorized modifications across different organizational projects.
The product performs an operation at a privilege level that is higher than the minimum level required, which creates new weaknesses or amplifies the consequences of other weaknesses.
New weaknesses can be exposed because running with extra privileges, such as root or Administrator, can disable the normal security checks being performed by the operating system or surrounding environment. Other pre-existing weaknesses can turn into security vulnerabilities if they occur while operating at raised privileges. Privilege management functions can behave in some less-than-obvious ways, and they have different quirks on different platforms. These inconsistencies are particularly pronounced if you are transitioning from one non-root user to another. Signal handlers and spawned processes run at the privilege of the owning process, so if a process is running as root when a signal fires or a sub-process is executed, the signal handler or sub-process will operate with root privileges.
