Summary
None · Investigating
Akamai is aware of the recently published F5/NGINX vulnerabilities (CVE-2026-15176, CVE-2026-97205, and CVE-2026-93479), and our teams are actively 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 on a Linode instance, we recommend following guidance from F5/NGINX and applying available patches. We will provide updates as additional information becomes available.
