What is CVE-2026-46585?

The Apache Camel Lucene Component is susceptible to an improper input validation and authorization bypass vulnerability. This flaw occurs when the camel-lucene producer processes input headers that are not properly filtered due to missing Camel prefix checks, allowing any HTTP client to manipulate the QUERY and RETURN_LUCENE_DOCS headers. Consequently, malicious users can execute unauthorized Lucene queries against the service’s full-text index, potentially exposing sensitive documents or consuming excessive CPU resources. The recommended mitigation involves upgrading to secure versions and adjusting header handling in routes.

Affected Version(s)

Apache Camel Lucene 4.0.0 < 4.14.8

Apache Camel Lucene 4.15.0 < 4.18.3

Apache Camel Lucene 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.
