CVE-2026-46585 Apache CVE debrief

The CVE record describes a vulnerability in Apache Camel's Lucene component, allowing for improper input validation and authorization bypass. An attacker could exploit this by setting the QUERY header in an HTTP request, leading to potential unauthorized access to documents in the full-text index. This vulnerability affects Apache Camel versions 4.0.0 to 4.14.8, 4.15.0 to 4.18.3, and 4.19.0 to 4.21.0. Users of these versions should be aware of this vulnerability and take steps to mitigate it.

Who should care

Users of Apache Camel, particularly those using versions 4.0.0 to 4.14.8, 4.15.0 to 4.18.3, and 4.19.0 to 4.21.0, should be aware of this vulnerability and take steps to mitigate it.

Technical summary

The camel-lucene producer reads the search phrase from an Exchange header (LuceneConstants.HEADER_QUERY) whose value was the plain string QUERY. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy let them pass from an inbound HTTP request straight into the Exchange. In a route that exposes a Lucene query operation behind an HTTP consumer, any HTTP client could therefore set the QUERY header and have its value executed against the full-text index, overriding the query the route intended to run.

Defensive priority

High

Recommended defensive actions

  • Upgrade to version 4.21.0 or later
  • If using 4.14.x LTS releases, upgrade to 4.14.8
  • If using 4.18.x releases, upgrade to 4.18.3
  • Strip attacker-controllable headers before the Lucene producer
  • Set the query from a trusted source
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
