Detailsinfo

A vulnerability was found in NCEAS Metacat up to 3.4.1. It has been declared as problematic. Affected by this vulnerability is the function MetacatSolrIndex.query of the component SolrJ. The manipulation of the argument qt with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. The summary by CVE is:

Metacat is data repository software that helps researchers preserve, share, and discover data. Prior to 3.4.2, MetacatSolrIndex.query forwards the client-controlled qt parameter through Apache SolrJ from search endpoints such as /d1/mn/v2/query/solr/ to its privileged Solr backend. An unauthenticated client can select the /admin/file handler, and SolrJ reformats the parameter into a request accepted even when handleSelect=false is configured on Solr 7.0 or later. When Solr returns the selected core configuration file, Metacat embeds the raw content in an XML processing error response, disclosing internal files such as solrconfig.xml and enabling infrastructure profiling. This issue is fixed in version 3.4.2.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-50022 since 06/03/2026. The exploitation appears to be easy. The attack can be launched remotely.
