Overview
Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') via the improper handling of HTTP headers with the SolrParam. and SolrField. prefixes. An attacker can manipulate Solr query parameters or inject arbitrary document fields by sending specially crafted HTTP requests, potentially causing the server to make requests to attacker-controlled URLs or alter indexed data. This is only exploitable if an HTTP consumer is bridged to a solr: producer and the consumer is unauthenticated.
Workaround
This vulnerability can be mitigated by stripping the SolrParam.* and SolrField.* headers from any untrusted ingress before the solr: producer, and setting required Solr parameters and fields from a trusted source in the route.
