The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

Jetty 8.1.0.RC2 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.

Directory traversal vulnerability in the HTTP server in Mort Bay Jetty 5.1.14, 6.x before 6.1.17, and 7.x through 7.0.0.M2 allows remote attackers to access arbitrary files via directory traversal sequences in the URI.

Cross-site scripting (XSS) vulnerability in Mort Bay Jetty before 6.1.17 allows remote attackers to inject arbitrary web script or HTML via a directory listing request containing a ; (semicolon) character.

Unspecified vulnerability in Jetty before 5.1.6 allows remote attackers to obtain source code of JSP pages, possibly involving requests for .jsp files with URL-encoded backslash ("%5C") characters. NOTE: this might be the same issue as CVE-2006-2758.
