CVE-2025-12764

There is a path traversal vulnerability using symbolic links in pgAdmin 4 File Manager. An authenticated user can create a symbolic link in their directory pointing outside of it, allowing data to be written to any path accessible by the pgAdmin process.

In pgAdmin 4 FileBackedSessionManager, there is a vulnerability to deserialization of untrusted data, which can lead to remote code execution at the operating system level. This issue arises from the lack of proper integrity checks before deserializing session file contents.

In pgAdmin 4 before version 9.15, there is an OS command injection vulnerability (CWE-78) in the Import/Export query export feature. An authenticated user could inject malicious commands, leading to arbitrary command execution on the pgAdmin server or arbitrary file writes.

A SQL injection vulnerability in the pgAdmin 4 Maintenance Tool allows an authenticated user with tools_maintenance permissions to execute arbitrary SQL commands on the PostgreSQL server. Exploiting this vulnerability could lead to privilege escalation and execution of operating system commands on the database host.

In pgAdmin 4, the 'webserver' authentication source was vulnerable because WebserverAuthentication.get_user() fell back to reading the username directly from inbound HTTP request headers when the WSGI/CGI environment lookup returned nothing. As a result, any client able to reach pgAdmin could supply that header itself and authenticate as any username, including an existing Administrator, without a password. The issue affects versions from 6.2 before 9.18 and only applies when 'webserver' is enabled in AUTHENTICATION_SOURCES.

A vulnerability in pgAdmin 4 allows remote code execution (RCE) via injection into the Import/Export Data tool. The validation function incorrectly handles backslashes in SQL strings, enabling bypass of protections and addition of a TO PROGRAM clause to psql commands.

A vulnerability in pgAdmin 4 (versions 9.13 to 9.16) allows bypassing the CVE-2026-12045 fix by injecting SQL queries into the AI assistant. An attacker can plant a malicious payload in an object read by the assistant, leading to execution of multiple SQL statements, including write or remote code execution.

In the adhoc_connect_server function in pgAdmin 4 9.0-9.16, when a non-owner user clones a server, all columns including credentials (passwords) and ownership flags are copied. This allows an attacker to take over the cloned server and use database passwords belonging to another user (e.g., an administrator).

A stored cross-site scripting vulnerability exists in pgAdmin 4 versions 6.0 through 9.15. Text returned by a PostgreSQL server (e.g., object names in errors or EXPLAIN fields) was passed verbatim to html-react-parser, allowing injection of arbitrary HTML, including iframes. An attacker controlling the server or creating a maliciously named object can hijack the victim's pgAdmin session.

In pgAdmin 4 versions 6.9 through 9.15, two SQL Editor endpoints lack authentication decorators, allowing unauthenticated attackers to trigger pickle deserialization from server sessions. Exploitation requires additional preconditions (knowledge of SECRET_KEY and write access to sessions directory) to achieve remote code execution.
