CVE-2025-8715 in PostgreSQL
Summary
by MITRE • 08/14/2025
Improper neutralization of newlines in pg_dump in PostgreSQL allows a user of the origin server to inject arbitrary code for restore-time execution as the client operating system account running psql to restore the dump, via psql meta-commands inside a purpose-crafted object name. The same attacks can achieve SQL injection as a superuser of the restore target server. pg_dumpall, pg_restore, and pg_upgrade are also affected. Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected. Versions before 11.20 are unaffected. CVE-2012-0868 had fixed this class of problem, but version 11.20 reintroduced it.

This vulnerability represents a critical code injection flaw in PostgreSQL's pg_dump utility that stems from improper handling of newline characters in object names during database dump operations. The vulnerability exists in the way PostgreSQL processes and serializes object names that contain newline characters, creating an opportunity for attackers to inject malicious content that gets executed during restore operations. The flaw specifically affects the psql meta-commands processing where crafted object names containing newlines can trigger unintended command execution when the dump is restored, making it a serious concern for database administrators and security professionals. This type of vulnerability falls under CWE-1107 which specifically addresses improper neutralization of newlines in input processing, and aligns with ATT&CK technique T1059.006 for execution through command injection.
The technical implementation of this vulnerability occurs when pg_dump encounters database objects with newline characters in their names, which are not properly sanitized or escaped during the dump creation process. When these malformed object names are later processed by pg_restore or psql during the restore operation, the newline characters can trigger the execution of arbitrary commands as the client operating system account running the restore process. This creates a privilege escalation scenario where a regular user on the origin server can potentially execute commands with the privileges of the psql process, which typically runs with the same permissions as the database user. The vulnerability affects multiple PostgreSQL versions including 17.6, 16.10, 15.14, 14.19, and 13.22, with the issue being reintroduced after a previous fix in version 11.20, making it a particularly concerning regression in the security posture of the database system.
The operational impact of this vulnerability extends beyond simple command execution to include potential SQL injection attacks when the restore target server has superuser privileges. Attackers can leverage this flaw to inject malicious SQL commands that execute with elevated privileges, potentially allowing full database compromise including data exfiltration, privilege escalation, and system-level access. The vulnerability affects not just individual database restores but also broader administrative operations through pg_dumpall and pg_upgrade utilities, making it a systemic threat to PostgreSQL deployments. Organizations using affected versions face significant risk as the attack vector requires minimal privileges on the source server to execute potentially devastating operations on the target system, making it particularly dangerous in environments where database administrators have elevated access rights.
Mitigation strategies for this vulnerability require immediate patching of affected PostgreSQL versions to the latest secure releases, with particular attention to the specific version boundaries mentioned in the CVE. Organizations should implement strict object naming conventions that prohibit newline characters in database object names, though this may not fully address the vulnerability in all scenarios. Network segmentation and privilege separation should be enforced to limit the potential impact of successful exploitation, ensuring that database restore operations run with minimal necessary privileges. Additionally, monitoring systems should be enhanced to detect unusual pg_dump and pg_restore activities, particularly when dealing with objects that might contain special characters or when restore operations are performed by unexpected users or processes. The vulnerability demonstrates the importance of maintaining comprehensive input validation across all database utilities and the necessity of thorough regression testing when implementing security fixes to prevent the reintroduction of previously addressed flaws.
