Pgadmin 4 · Pgadmin 4 · CVE-2026-7815
**Name of the Vulnerable Software and Affected Versions**
pgAdmin 4 versions prior to 9.15
**Description**
An SQL injection exists in the Maintenance Tool where four user-supplied JSON fields—`buffer usage limit`, `vacuum parallel`, `vacuum index cleanup`, and `reindex tablespace`—are concatenated directly into the rendered VACUUM, ANALYZE, or REINDEX command and passed to psql --command. An authenticated user with the tools maintenance permission can break out of the option syntax to execute arbitrary SQL on the connected PostgreSQL server. This can further lead to operating-system command execution on the database host by invoking the COPY ... TO PROGRAM command.
**Recommendations**
Update to version 9.15 or later.
