Vulnerability in org.apache.camel:camel-irc (CVE-2026-49097)

Summary

Vulnerability in org.apache.camel:camel-irc (CVE-2026-49097). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 4.21.0 or later.

Original description

The description as published by the source.

Improper Input Validation, Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in Apache Camel IRC component.

The camel-irc producer chooses the destination of an outgoing IRC message from the irc.sendTo Exchange header (the constant IrcConstants.IRC_SEND_TO, value irc.sendTo); when that header is present it overrides the channel list configured on the endpoint, and the message is sent only to the specified destination. This and the component's other control headers (irc.target, irc.messageType, irc.user.*, irc.num, irc.value) used plain, non-Camel-prefixed values. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into an irc: producer, any HTTP client could therefore set the irc.sendTo header and redirect a message that the route intended for a configured channel to an arbitrary IRC channel or user - exfiltrating the message content to an attacker-chosen nickname, leaking it into a public channel, or delivering messages that appear to come from the bot. No credentials are required when the bridging consumer is unauthenticated.
This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.
