DescriptionCVE.org

Stored cross-site scripting (XSS) vulnerability in pgAdmin 4 Browser Tree and Explain Visualizer modules.

User-controlled PostgreSQL object names (database, schema, table, column, etc.) were assigned to DOM elements via innerHTML, allowing crafted object names containing HTML markup to execute attacker-supplied JavaScript in the browser of any pgAdmin user who navigated to or executed EXPLAIN over the malicious object.

Fix replaces innerHTML with textContent.

This issue affects pgAdmin 4: before 9.15.

AnalysisAI

Stored cross-site scripting (XSS) in pgAdmin 4 before version 9.15 allows authenticated administrators to execute arbitrary JavaScript in the browsers of other pgAdmin users by crafting malicious PostgreSQL object names (databases, schemas, tables, columns) that are rendered unsafely via innerHTML in the Browser Tree and Explain Visualizer modules. The vulnerability requires administrator privileges and user interaction (navigation to or EXPLAIN execution over the malicious object), limiting real-world exploitation scope despite the network attack vector.

Technical ContextAI

pgAdmin 4 is a web-based PostgreSQL management interface that displays database object hierarchies in a browser tree UI and provides EXPLAIN plan visualization. The vulnerability stems from unsafe DOM manipulation: user-controlled PostgreSQL object names (which are retrieved from the database and trusted by the application) are assigned directly to DOM elements using innerHTML rather than textContent. This causes HTML/JavaScript embedded in object names to be parsed and executed as active code. The CWE classification was not provided, but this is a classic DOM-based stored XSS (CWE-79: Improper Neutralization of Input During Web Page Generation). The affected CPE is cpe:2.3:a:pgadmin.org:pgadmin_4:*:*:*:*:*:*:*:*, covering all versions before 9.15.

RemediationAI

Upgrade pgAdmin 4 to version 9.15 or later immediately - this is the primary fix and replaces the unsafe innerHTML calls with textContent to prevent HTML/JavaScript interpretation. Organizations unable to upgrade immediately should restrict pgAdmin administrative access to trusted users only and monitor for suspicious database object creation attempts (names containing script tags, event handlers, or encoded HTML). The fix can be verified by reviewing the GitHub PR to confirm textContent replacement in the Browser Tree and Explain Visualizer modules. No workarounds are available short of disabling the affected modules (Browser Tree and Explain plans), which would severely degrade pgAdmin functionality.
