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":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
