When Jetty's HttpClient make a request to a server through a forward proxy, the server may reply with a 407 (Proxy Authentication Required). The client mistakenly interprets the 407 as coming from the proxy, so it re-sends the request with the Proxy-Authentication header, which a...

HighCVSS 8.2 EPSS 0.39%
In Eclipse Jetty, HttpClient may receive a redirect of the form: /secure/../evil If an attacker is able to control the redirects, then HttpClient matches authentication credentials against /secure rather than normalizing the path to /evil, and will therefore follow the redirect s...

In Eclipse Jetty, TryPathsHandler and TryFilesFilter can be configured to forward requests to template URIs such as index?p=$path, where $path is the request path in context. However, URI paths may contain characters that are reserved in URI queries so that a path of /s&a=1 when...

A client may issue HTTP/2 requests to a Jetty server that result in blocking writes that are never unblocked, eventually causing all threads to be blocked and the whole server to become unresponsive. This is caused by a race condition in the server when handling RST_STREAM frames...

HighCVSS 8.3 EPSS 0.31%
A client may issue specially crafted HTTP/1.1 chunked requests to a Jetty server that cause Jetty and an intermediary proxy to interpret different request boundaries, potentially resulting in HTTP request smuggling. This is caused by Jetty accepting a lone LF character as a termi...

HighCVSS 8.7 EPSS 0.45%
A client may send a WebSocket frame with an unknown opcode and a very large declared payload length, causing Jetty to attempt a large memory allocation and potentially exhaust the JVM heap. This occurs when auto-fragmentation is enabled, as unknown opcodes bypass the normal maxim...

In Eclipse Jetty, the Digest authentication server-side component uses ISO-8859-1 to encode the password as bytes. This was done because the initial specification for HTTP did not specify explicitly a charset, and it was assumed to be ISO-8859-1 for historical reasons. If the pas...

For requests that have a body, but reading the body may end up in reading 0 bytes, there is a buffer leak. This is particularly the case for 100-Continue, but any request where the network is slow can leak.

In Eclipse Jetty, an HTTP URI of this form: /public;/../admin/secret.txt results in an unresolved path of: /public/../admin/secret.txt instead of the expected: /admin/secret.txt Jetty itself is not affected, as it will not serve the secret.txt file because it will not pass the al...

In Eclipse Jetty, for HTTP/1, HTTP/2 and HTTP/3 requests, there is no strict check that the request authority (host and port) matches what provided in the Host header (if present). This was not enforced in earlier HTTP RFC (for example, in RFC 2616), but it is in the latest RFC (...

CVE-2026-10051 Eclipse Jetty: Cross-Request Leakage for trailers on HTTP/1.1 keep-alive connections
PublishedMediumCVSS 6.9 EPSS 0.43%In Eclipse Jetty, a first HTTP/1.1 request with trailers causes the server to retain the trailers in subsequent requests performed over the same connection. Subsequent request that do not have trailers report the trailers of the first request. Subsequent request that do have trai...

In Eclipse Jetty, the class JASPIAuthenticator initiates the authentication checks, which set two ThreadLocal variable. Upon returning from the initial checks, there are conditions that cause an early return from the JASPIAuthenticator code without clearing those ThreadLocals. A...

In Eclipse Jetty, versions 12.0.0-12.0.31 and 12.1.0-12.0.5, class GzipHandler exposes a vulnerability when a compressed HTTP request, with Content-Encoding: gzip, is processed and the corresponding response is not compressed. This happens because the JDK Inflater is allocated fo...

The Jetty URI parser has some key differences to other common parsers when evaluating invalid or unusual URIs. Differential parsing of URIs in systems using multiple components may result in security by-pass. For example a component that enforces a black list may interpret the UR...
