CVE-2026-76238
HighCVSS 7.2Summary
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 with ttl_seconds=0 to expire facts across all tenants, or use dry_run to obtain cross-tenant fact counts and existence information.
Risk Assessment
An attacker can break tenant data isolation, causing unauthorized expiration of facts or disclosure of information about other tenants' data.
Recommendation
Upgrade stigmem to version 0.9.0a12 or later, which fixes the vulnerability, and restrict access to the decay sweep endpoint to trusted administrators only.
