What is CVE-2026-49097?

The Apache Camel IRC component is vulnerable due to improper input validation that allows an attacker to manipulate the destination of IRC messages. This occurs when an HTTP route passes headers from an inbound request without proper filtering, allowing any client to redirect messages meant for a configured channel to an arbitrary IRC channel or user. This could result in message exfiltration or delivery of malicious content appearing to be from the bot. Users are advised to upgrade to appropriate patched versions to mitigate this issue.

Affected Version(s)

Apache Camel 4.0.0 < 4.14.8

Apache Camel 4.15.0 < 4.18.3

Apache Camel 4.19.0 < 4.21.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
