Users are recommended to upgrade to version 24.09.08, which fixes this issue.\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":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
