Apache Camel: HTTP producers resolve property placeholders in message-supplied URI override headers

Type: advisorySource: Official CVE List1 source record

Improper Neutralization of Special Elements Used in a Template Engine and Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Camel HTTP, Netty HTTP, Undertow and Vert.x HTTP components. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Camel HTTP producer families let an inbound message override the endpoint URI through the CamelHttpUri and CamelRestHttpUri headers, and then passed that message-supplied string through CamelContext.resolvePropertyPlaceholders() before using it. Property-placeholder resolution is a configuration-resolution facility, not a URI-parsing step: it reaches operating-system environment variables, JVM system properties, every PropertiesFunction registered on the classpath - including the secret functions - and, through camel-bean, the invocation of a no-argument method on any bean in the registry. Applying it to Exchange content therefore turned a URI string into a configuration- and bean-evaluation context. A route author opted into none of this: a plain static to("http://backend/api") was sufficient. Seven call sites were affected: HttpHelper.createURL and HttpHelper.createMethod in camel-http-common, HttpMethodHelper.createMethod in camel-http, VertxHttpHelper.resolveHttpURI in camel-vertx-http, UndertowHelper.createURL and UndertowHelper.createMethod in camel-undertow, and NettyHttpHelper.createURL in camel-netty-http. The bridgeEndpoint option did not bound the exposure: it su
