Vulnerability Title
stigmem before 0.9.0a12 Cross-Tenant BOLA via Tombstones
Vulnerability 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.

Vulnerability Title
eidetic-labs stigmem 授权问题漏洞
Vulnerability Description
eidetic-labs stigmem是eidetic-labs组织的一款威胁情报网络产品。 eidetic-labs stigmem 0.9.0a12之前版本存在授权问题漏洞,该漏洞源于跨租户对象级授权缺陷,在RTBF墓碑机制中issue_tombstone默认将租户设置为"default"而非调用者的租户,且读取抑制路径缺少tenant_id谓词,导致删除记录被写入错误租户,墓碑抑制跨租户盲目应用,可能隐藏其他租户的事实或未能隐藏正确租户的事实,破坏数据隔离和RTBF保证。
