Summary
Metacat is data repository software that contains an unauthenticated SQL injection vulnerability in the /harvesterRegistration endpoint in versions 2.0.0 and above. Exploiting this vulnerability allows full read/write/execute access in the Metacat database context.
Risk Assessment
This vulnerability may lead to unauthorized access and modification of data, posing a serious threat to the integrity and confidentiality of data within the organization.
Recommendation
It is recommended to upgrade to Metacat version 3.0.0 or newer to remediate this vulnerability. Additionally, implementing LDAP identity verification mechanisms is advisable for enhanced security.
Other vulnerabilities in Metacat
See all- CVE-2026-48528Critical
Metacat versions 2.0.0 through 3.4.0 contain an unauthenticated SQL injection vulnerability in the `/cn/v1/object` and `/cn/v2/object` REST API endpoints. The `nodeId` parameter is unsanitized and concatenated into SQL queries, allowing attackers to execute arbitrary SQL, including reading, modifying, and deleting data from the PostgreSQL database. SQL errors are reflected in XML messages, enabling data exfiltration.
- CVE-2026-47754Critical
Metacat versions 2.x through 2.19.1 and all 1.x versions contain an unauthenticated path traversal in the `archiveEntryName` parameter of the `action=read` endpoint in the legacy 1.x API. An attacker can read any file accessible to the Tomcat process by sending a single GET request, as path validation is missing and the permission check is commented out.
- CVE-2026-50022Medium
Metacat is data repository software for researchers. 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. This issue is fixed in version 3.4.2.
Original NVD description (English source)
Metacat is data repository software that helps researchers preserve, share, and discover data. Versions 2.0.0 and and above contain an unauthenticated SQL injection in the /harvesterRegistration endpoint. HarvesterRegistration.dbInsert() builds an INSERT against HARVEST_SITE_SCHEDULE via string concatenation, using a quoteString() helper that performs raw single-quote wrapping without escaping. Three request parameters reach the sink: unit, contactEmail, and documentListURL. The servlet does not verify a real LDAP identity. Allowing the vulnerable insert to proceed. Since the PostgreSQL backend permits stacked queries via Statement.executeUpdate(), this vulnerability allows full read/write/execute access in the Metacat database context. The vulnerability was remediated in Metacat 3.0.0.
