DelegatorFactory's internal cache retains every delegator name it is asked to resolve, including ones that fail to resolve, so an unauthenticated attacker could submit a stream of arbitrary tenant IDs to grow this cache without bound, driving unnecessary memory and database load.\n\n## Affected\n\n- `apache_ofbiz < 24.09.08`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
