NewCVE-2026-85254 (opens in a new tab)How to fix?
Upgrade org.apache.camel:camel-platform-http-main to version 4.18.5, 4.22.1 or higher.
Overview
Affected versions of this package are vulnerable to Improper Handling of Case Sensitivity via the enhanceHeaderFilterStrategyToSkipHttpRequestHeaders() function in the Platform HTTP component. An attacker can cause caller-supplied values in common request headers that the filter is meant to suppress to be echoed in responses by varying the header-name casing; on HTTP/2, lowercase names make this happen for every such header sent. The echoed content can enable response-splitting or cache-poisoning attacks against intermediaries.
Workarounds
- Strip
Authorization,Cookie,Proxy-Authorization, and other affected common request headers before they reach the Camel endpoint to prevent them from being echoed in responses. - Remove those headers from responses in the Camel route to prevent the vulnerable endpoint from reflecting them to clients or intermediaries.
