CVE-2025-66373 describes an HTTP request smuggling vulnerability in Akamai Ghost, affecting Akamai CDN edge servers prior to November 17, 2025. This flaw, categorized as CWE-444, allows an attacker to hide a smuggled request within superfluous bytes when Akamai Ghost incorrectly processes malformed chunked request bodies, forwarding them to the origin server. Rated Medium with a CVSS score of 4.8, exploitation requires high attack complexity and could lead to limited confidentiality and integrity impacts, depending on the origin server's behavior. There is no evidence of active exploitation, public exploit code, or Metasploit/Nuclei modules, though it has garnered minimal community discussion and media coverage.
