Metacat has an unauthenticated SQL injection vulnerability

Published Jun 15, 2026 · Updated Jun 15, 2026 · Assigned by GitHub_M

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.
