Summary Eclipse Jetty: Cross-Request Leakage for trailers on HTTP/1.1 keep-alive connections ### Description > FINDING — MEDIUM (HTTP/1.1 keep-alive connections with trailers) > HttpConnection._trailers Cross-Request Leakage (Never Reset Between Requests) > > Location: > jetty-core/jetty-server/src/main/java/org/eclipse/jetty/server/internal/ > HttpConnection.java:107, 1157-1161, 1170 > > Detail: > _trailers (line 107) is a connection-scoped HttpFields.Mutable field. > parsedTrailer() (line 1157) populates it when request N carries HTTP trailers. > messageComplete() (line 1170) checks "if (_trailers != null)" — evaluates true > from request N's data — and stamps it onto request N+1. > > Grep confirms: ZERO occurrences of "_trailers = null" in entire HttpConnection.java. > > Scenario: > Request N: POST /upload (trailers: X-Checksum: abc123) > Request N+1: GET /data (no trailers) > app: request.getTrailers() on N+1 → returns {X-Checksum: abc123} ← STALE > > Application logic branching on getTrailers() != null produces incorrect behavior. > Not cross-connection (same keep-alive connection only). > > More dangerous scenario: TOCTOU — trailer passes check, target swapped before use. ### Workarounds Do not rely on HTTP request trailers for security-sensitive logic, or disable persistent connections by closing the connection after each HTTP/1.1 request.
