CVE-2026-76238: Incorrect Authorization in eidetic-labs stigmem
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.
AI Analysis
Technical Summary
CVE-2026-76238 describes an incorrect authorization vulnerability in eidetic-labs stigmem prior to version 0.9.0a12. The flaw exists in the decay sweep endpoint, where authenticated attackers with write credentials for a single tenant can submit POST requests with ttl_seconds=0 to expire facts across all tenants or use the dry_run parameter to retrieve fact counts and existence information from other tenants. This indicates a broken object level authorization control allowing cross-tenant operations that should be restricted.
Potential Impact
The vulnerability enables authenticated users with limited tenant write access to perform unauthorized decay operations affecting all tenants, leading to potential data expiration and cross-tenant information disclosure. This can disrupt data integrity and confidentiality across tenants in a multi-tenant environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict write access to trusted users only and monitor for unusual decay sweep endpoint activity. Avoid using the decay sweep endpoint with ttl_seconds=0 or dry_run parameters unless necessary and authorized.
