This vulnerability enables attackers to expire facts for all tenants or gather sensitive information about cross-tenant data. Organizations using stigmem should prioritize patching this issue to prevent potential data breaches and unauthorized data manipulation.

Original NVD Description

stigmem versions before 0.9.0a12 contain a broken object level authorization vulnerability in the decay sweep endpoint that allows authenticated attackers with write credentials for one tenant to execute decay operations affecting all tenants. Attackers can submit POST requests to the decay sweep endpoint with ttl_seconds=0 to expire facts across all tenants, or use dry_run to obtain cross-tenant fact counts and existence information.
