| CVE-2023-44487 | Hig | 0.65 | 7.5 | 1.00 | KEV | Oct 10, 2023 | 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. | |
| CVE-2017-7658 | Cri | 0.65 | 9.8 | 0.21 | Jun 26, 2018 | In Eclipse Jetty Server, versions 9.2.x and older, 9.3.x (all non HTTP/1.x configurations), and 9.4.x (all HTTP/1.x configurations), when presented with two content-lengths headers, Jetty ignored the second. When presented with a content-length and a chunked encoding header, the… | ||

The chunk length parsing was vulnerable to an integer overflow. Thus a large chunk size… | ||
| CVE-2016-4800 | Cri | 0.64 | 9.8 | 0.06 | Apr 13, 2017 | The path normalization mechanism in PathResource class in Eclipse Jetty 9.3.x before 9.3.9 on Windows allows remote attackers to bypass protected resource restrictions and other security constraints via a URL with certain escaped characters, related to backslashes. | ||
| CVE-2015-2080 | Hig | 0.58 | 7.5 | 0.75 | Oct 7, 2016 | The exception handling code in Eclipse Jetty before 9.2.9.v20150224 allows remote attackers to obtain sensitive information from process memory via illegal characters in an HTTP header, aka JetLeak. | ||
