CVE-2026-49365Public exploitNetwork attack vector

Information disclosure via unmuted exception stack traces

Published Jul 6, 2026 · Updated Jul 6, 2026

Information disclosure in Apache Camel Netty HTTP allows remote attackers to read full Java stack traces from affected 4.x servers. DefaultNettyHttpBinding writes a route-processing Throwable into the response because the uninitialized muteException boolean defaults to false. Remote attackers must reach a camel-netty-http endpoint and trigger a processing error; affected ranges are 4.0.0 through 4.14.7, 4.15.0 through 4.18.2, and 4.19.0 through 4.20.x.
