Summary

Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), Authorization Bypass Through User-Controlled Key vulnerability in Apache Camel Salesforce Component.

The camel-salesforce producer resolves its operation parameters - the SOQL query, the SOSL search, the target SObject name and id, the Apex REST URL and method, and the Apex query parameters - from Exchange message headers, reading the header in preference to the value configured on the endpoint (AbstractSalesforceProcessor.getParameter() reads the header first and uses the endpoint configuration only as a fallback).

The control-header constants in SalesforceEndpointConfig (for example SOBJECT_QUERY = sObjectQuery, SOBJECT_SEARCH = sObjectSearch, SOBJECT_NAME = sObjectName, SOBJECT_ID = sObjectId, APEX_URL = apexUrl, APEX_METHOD = apexMethod, and the apexQueryParam. prefix) 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.

Is CVE-2026-49099 exploited?

Mitigation checklist

Recommended fix / mitigation
  • Users are recommended to upgrade to version 4.21.0, which fixes the issue.
  • If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8.
  • If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3.
  • For deployments that cannot upgrade immediately, strip the Salesforce control headers from any untrusted ingress before the salesforce: producer (for example removeHeaders('sObject*') and removeHeaders('apex*') at the start of the route), and set the query, SObject and Apex parameters from a trusted source.
