AI-Generated

Grashjs Atlas CMMS versions prior to 1.6.0 are vulnerable to a Broken Object Level Authorization issue, allowing authenticated users from one tenant to access and modify company records of another tenant by simply altering the numeric ID in the /company/{id} endpoint. This lack of tenant-level ownership checks poses a significant risk of unauthorized data exposure and manipulation. Organizations using this application should prioritize updates to mitigate potential cross-tenant data breaches.

Original NVD Description

A Broken Object Level Authorization vulnerability exists in Grashjs Atlas CMMS prior to v1.6.0.

The application does not enforce tenant-level ownership checks when accessing or updating company objects, allowing cross-tenant access and modification of company profile data.
