CVE-2017-7656 is a high-severity vulnerability in Eclipse Jetty versions 9.2.x and older, all 9.3.x configurations, and specific 9.4.x configurations, concerning improper handling of HTTP/0.9 requests. An attacker could craft an HTTP/1-style request declaring HTTP/0.9, which, if passed through an intermediary, could lead to cache poisoning by allowing arbitrary content generation in the response. The CVSS score is 7.5 (High), indicating a network-based attack with low complexity and high impact on integrity. There is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.
