DescriptionCVE.org

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.

AnalysisAI

HTTP request smuggling in Akamai Ghost CDN edge servers before 2026-02-06 allows remote attackers to craft malicious requests with conflicting hop-by-hop headers that cause improper message framing when forwarded to origin servers. An attacker can exploit this to inject unauthorized requests or bypass security controls by manipulating how the origin server interprets the request body. No patch is currently available.
