SQL injection vulnerability in pgAdmin 4 Maintenance Tool.

Four user-supplied JSON fields (buffer_usage_limit, vacuum_parallel, vacuum_index_cleanup, reindex_tablespace) were concatenated directly into the rendered VACUUM/ANALYZE/REINDEX command and passed to psql --command. An authenticated user with the tools_maintenance permission could break out of the option syntax and execute arbitrary SQL on the connected PostgreSQL server. The injected SQL could in turn invoke COPY ... TO PROGRAM to escalate to operating-system command execution on the database host.

Fix introduces server-side allow-listing of all four fields and switches reindex_tablespace from manual quoting to the qtIdent filter.

This issue affects pgAdmin 4: before 9.15.

AnalysisAI

SQL injection in pgAdmin 4 Maintenance Tool allows authenticated users with tools_maintenance permission to execute arbitrary SQL and escalate to operating-system command execution on PostgreSQL database hosts. Four JSON fields (buffer_usage_limit, vacuum_parallel, vacuum_index_cleanup, reindex_tablespace) are concatenated unsafely into VACUUM/ANALYZE/REINDEX commands passed to psql. Attackers can break out of option syntax, inject SQL statements, and leverage PostgreSQL's COPY ... TO PROGRAM to achieve OS-level code execution. Fixed in version 9.15 via server-side allow-listing and proper input sanitization using qtIdent filter. EPSS data not available; no public exploit identified at time of analysis.

Technical ContextAI

pgAdmin 4 is the web-based administration and development platform for PostgreSQL databases. The Maintenance Tool generates database maintenance commands (VACUUM, ANALYZE, REINDEX) from user-supplied parameters. The vulnerability stems from unsafe string concatenation of four JSON input fields directly into SQL command strings before passing them to the psql command-line client via the --command flag. This classic second-order injection occurs because user-controlled input flows through the web application into dynamically constructed SQL without proper escaping or parameterization. The reindex_tablespace field relied on manual quoting instead of PostgreSQL's qtIdent identifier-quoting function. When these malformed commands reach the PostgreSQL server, attackers can inject arbitrary SQL, including COPY ... TO PROGRAM statements that invoke shell commands on the database host operating system, bridging from SQL injection to remote code execution.

RemediationAI

Upgrade to pgAdmin 4 version 9.15 or later, which implements server-side allow-listing for buffer_usage_limit, vacuum_parallel, vacuum_index_cleanup, and reindex_tablespace fields and replaces manual quoting with the qtIdent filter for identifier sanitization. Download the patched version from https://www.pgadmin.org/download/ or update via your package manager (apt, yum, Homebrew, Docker registry). Verify successful upgrade by checking Help > About shows version 9.15+. If immediate patching is not feasible, implement compensating controls: revoke tools_maintenance permission from all non-administrative users via pgAdmin's role management interface (trade-off: breaks legitimate maintenance workflows for power users); restrict pgAdmin access to trusted administrator workstations via firewall rules or VPN (trade-off: reduces operational flexibility); enable PostgreSQL query logging and monitor for suspicious COPY TO PROGRAM or shell command invocations in logs (trade-off: performance overhead and delayed detection). Network segmentation between pgAdmin servers and database hosts limits lateral movement post-compromise but does not prevent initial SQL injection. Review and minimize use of PostgreSQL superuser privileges for connections initiated from pgAdmin. Full technical details and patch commits are available in the referenced GitHub issue.
