This significant security flaw enables authentication bypass and Server-Side Request Forgery (SSRF), earning a high CVSS score of 9.8. Notably, a patch previously released to address CVE-2023-49070 was found to be ineffective, inadvertently leaving the system susceptible to this new vulnerability.


At OP Innovate, we strongly advise all users of Apache OFBiz to immediately upgrade to version 18.12.11. This latest version contains essential security fixes that address CVE-2023-51467, helping to safeguard against potential exploits.

Apache OFBiz is a widely-used, open-source Enterprise Resource Planning (ERP) system, offering versatile business solutions. The emergence of CVE-2023-51467 came to light following a patch release on December 4, 2023, for CVE-2023-49070, highlighting the need for continuous monitoring and updating of security measures.
