CVE-2026-10051: CWE-200 in Eclipse Foundation Eclipse Jetty
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 trailers report the union of trailers of the first request and the current request.
AI Analysis
Technical Summary
CVE-2026-10051 describes an information disclosure vulnerability (CWE-200) in Eclipse Jetty HTTP server. When a first HTTP/1.1 request on a connection includes trailers, the server retains these trailers and incorrectly includes them in subsequent requests over the same connection. Requests without trailers report the trailers from the first request, while requests with trailers report the union of the first and current request trailers. This behavior can lead to unintended exposure of HTTP trailer header information across requests.
Potential Impact
The vulnerability allows information leakage of HTTP trailer headers from one request to subsequent requests on the same connection. This could expose sensitive metadata or information intended only for the initial request to other clients or requests, potentially violating confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch is currently documented. Users should monitor Eclipse Foundation advisories for updates and consider mitigating by disabling HTTP/1.1 request trailers or isolating connections if possible until a fix is available.
