Overview

CVE-2026-48114 is a critical-severity vulnerability. It was published on June 15, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
