   Akamai is aware of the recently published F5/NGINX vulnerabilities (CVE-2026-15176, CVE-2026-97205, and CVE-2026-93479), and our teams are investigating their potential impact across our platform and infrastructure.F5 has released out-of-band security patches addressing three critical severity vulnerabilities in NGINX Open Source and NGINX Plus. These vulnerabilities may allow unauthenticated attackers to trigger heap buffer overflows, which could cause a denial of service or potential remote code execution if ASLR is bypassed.If you are running a vulnerable version of NGINX Open Source or NGINX Plus, we recommend following guidance from F5/NGINX and applying available patches.We will post more details for customers and partners with a valid Control Center login at https://community.akamai.com/customers/s/group/0F90f000000DFgx/service-incident-notifications as additional information becomes available. If you have questions or are experiencing an impact due to this issue, please use the Support Center on Akamai Community, or Akamai Control Center, to contact Akamai Technical Support.
