CVE-2026-48114Network attack vector

Database compromise via unescaped harvester registration parameters

Published Jun 15, 2026 · Updated Jun 15, 2026

SQL injection in Metacat 2.0.0 through 2.19.1 allows remote attackers to read and alter database data via harvesterRegistration. HarvesterRegistration.dbInsert() concatenates unit, contactEmail, and documentListURL into an INSERT, while quoteString() wraps raw single quotes without escaping. No valid LDAP identity is required, and PostgreSQL stacked queries permit full database-context reads, writes, and statement execution.
