Summary
In pgAdmin 4 server mode, multiple endpoints fetched user-owned objects without filtering by the requesting user's identity, allowing an authenticated user to access another user's private servers, server groups, background processes, and debugger arguments by guessing object IDs. The Shared Servers feature had additional issues including credential leakage, privilege escalation via writable passexec_cmd enabling arbitrary command execution, and owner-data corruption.
Risk Assessment
An authenticated user can access other users' resources, steal credentials, or execute arbitrary commands in the owner's process context, posing a serious threat to confidentiality and integrity.
Recommendation
Upgrade pgAdmin 4 to version 9.15 or later, which centralizes access control and restricts writes to owner-only fields.
Other vulnerabilities in pgAdmin 4
See all- CVE-2026-116241Critical
pgAdmin 4 before 9.19 contains a bypass of the CVE-2026-17566 fix in the Import/Export Data tool. Improper validation of a backslash inside a double-quoted identifier hides a closing parenthesis and executes a TO PROGRAM clause via psql on the pgAdmin host with the OS account privileges.
- CVE-2026-86863Critical
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.
- CVE-2026-17566Critical
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.
- CVE-2026-17351Critical
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.
- CVE-2026-17349Critical
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).
- CVE-2026-12048Critical
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.
- CVE-2026-12046Critical
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.
- CVE-2026-12045Critical
A vulnerability in the pgAdmin 4 AI Assistant allows an attacker who can influence database content read by the assistant to execute arbitrary SQL with the privileges of the pgAdmin user's database role. The flaw stems from missing validation of LLM-generated queries, enabling bypass of read-only mode via injection of commands like COMMIT or ROLLBACK.
- CVE-2025-13780Critical
pgAdmin versions up to 9.10 are affected by a Remote Code Execution (RCE) vulnerability that occurs when running in server mode and performing restores from PLAIN-format dump files. This issue allows attackers to inject and execute arbitrary commands on the server hosting pgAdmin.
- CVE-2025-12762Critical
pgAdmin versions up to 9.9 are affected by a Remote Code Execution (RCE) vulnerability when running in server mode and performing restores from PLAIN-format dump files. Attackers can inject and execute arbitrary commands on the server hosting pgAdmin.
Original NVD description (English source)
Authorization vulnerability in pgAdmin 4 server mode affecting Server Groups, Servers, Shared Servers, Background Processes, and Debugger modules. Multiple endpoints fetched user-owned objects without filtering by the requesting user's identity. An authenticated user could access another user's private servers, server groups, background processes, and debugger function arguments by guessing object IDs. Additionally, the Shared Servers feature contained multiple issues including credential leakage (passexec_cmd, passfile, SSL keys), privilege escalation via writable passexec_cmd (a shell command executed when establishing the connection) allowing arbitrary command execution in the owner's process context, and owner-data corruption via SQLAlchemy session mutations. Several owner-only fields (passexec_cmd, passexec_expiration, db_res, db_res_type) were writable by non-owners through the API, and additional fields (kerberos_conn, tags, post_connection_sql) lacked per-user persistence so non-owner edits mutated the owner's record. Fix centralises access control via a new server_access module, scopes all user-owned models with a UserScopedMixin, returns HTTP 410 from connection_manager when access is denied in server mode, suppresses owner-only fields for non-owners across the merge / API response / ServerManager paths, and adds an explicit owner-only write guard. The remediation landed in two pull requests; both are referenced. This issue affects pgAdmin 4: before 9.15.
