NEW - DEC 22, 2025: A patch to address CVE-2025-66516 in Apache Tika packages used in Omnissa Access is available.

We have determined that Apache Tika ships with Omnissa Access in a way that significantly mitigates the severity of CVE-2025-66516. Administrative credentials are required to attempt exploitation and there are other safeguards in place that make exploitation more difficult, resulting in a Medium severity CVSS 3.1 score of 6.4/10.

We have made a patch available to update Apache Tika packages to fixed versions in Omnissa Access. Download Patch HW-250276-Appliance-24.12.1.0.zip from the Omnissa Access 24.12 Download page on Customer Connect.
