CyberRota Analysis
AI-GeneratedThe stigmem-node software prior to version 0.9.0a12 is vulnerable to a cross-tenant broken object level authorization flaw that compromises the right-to-be-forgotten (RTBF) mechanism. This vulnerability allows deletion records to be incorrectly attributed to the wrong tenant, potentially exposing sensitive data and undermining data isolation across multi-tenant deployments. Organizations using this software in a multi-tenant environment should prioritize upgrading to the fixed version to mitigate these risks.

Original NVD Description
stigmem-node before 0.9.0a12 contains a cross-tenant broken object level authorization (BOLA) flaw in the RTBF (right-to-be-forgotten) tombstone mechanism. issue_tombstone defaulted the tenant to "default" instead of the caller's tenant, allowing deletion records to be written to the wrong tenant, and the read-suppression path (_get_tombstone_filter and the tombstone scope cache) lacked a tenant_id predicate, so tombstone suppression was applied tenant-blind across fact queries and provenance reads. As a result, a tenant's deletion could be attributed to the wrong tenant and tombstone suppression could either hide facts belonging to other tenants or fail to hide facts within the correct tenant, undermining data isolation and RTBF guarantees. The issue is exploitable only on multi-tenant deployments running the opt-in stigmem-plugin-multi-tenant; single-tenant deployments are unaffected. Fixed in 0.9.0a12.
