Vulnerability details
In lunary-ai/lunary versions 1.2.2 through 1.2.25, an improper access control vulnerability allows users on the Free plan to invite other members and assign them any role, including those intended for Paid and Enterprise plans only. This issue arises due to…
more
insufficient backend validation of roles and permissions, enabling unauthorized users to join a project and potentially exploit roles and permissions not intended for their use. The vulnerability specifically affects the Team feature, where the backend fails to validate whether a user has paid for a plan before allowing them to send invite links with any role assigned. This could lead to unauthorized access and manipulation of project settings or data.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
