CVE-2026-26365: Akamai Ghost

Medium severity, CVSS 4.0. EPSS: 0.3% chance of exploitation in the next 30 days.

Akamai Ghost on Akamai CDN edge servers before 2026-02-06 mishandles processing of custom hop-by-hop HTTP headers, where an incoming request containing the header "Connection: Transfer-Encoding" could result in a forward request with invalid message framing, depending on the Akamai processing path. This could result in the origin server parsing the request body incorrectly, leading to HTTP request smuggling.
