Vulnerability from cvelistv5 – Published: 2025-11-13 21:13 – Updated: 2025-11-13 21:33

Summary

Directus is a real-time API and App dashboard for managing SQL database content. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 11.13.0 that allows users with `upload files` and `edit item` permissions to inject malicious JavaScript through the Block Editor interface. Attackers can bypass Content Security Policy (CSP) restrictions by combining file uploads with iframe srcdoc attributes, resulting in persistent XSS execution. Version 11.13.0 fixes the issue.

Severity ?

5.5 (Medium)

GHSA-VV2V-PW69-8CRF

Vulnerability from github – Published: 2025-11-14 21:45 – Updated: 2025-11-14 21:45

Summary

Directus is Vulnerable to Stored Cross-site Scripting

Details

Summary

A stored cross-site scripting (XSS) vulnerability exists that allows users with upload files and edit item permissions to inject malicious JavaScript through the Block Editor interface. Attackers can bypass Content Security Policy (CSP) restrictions by combining file uploads with iframe srcdoc attributes, resulting in persistent XSS execution.

Details

The vulnerability arises from insufficient sanitization in the Block Editor interface when processing JSON content containing HTML elements. The attack requires two permissions: - upload files - To upload malicious JavaScript files - edit item - To create or modify content with the Block Editor

Attack Vector:

JavaScript File Upload: Attackers upload a malicious JavaScript file via the files endpoint, obtaining a file ID accessible through the assets directory
Block Editor Exploitation: Using a JSON field with Block Editor interface, attackers inject raw HTML containing an iframe with srcdoc attribute that references the uploaded file
CSP Bypass: The iframe srcdoc technique circumvents existing CSP protections by creating a new document context that loads the uploaded script

The payload is injected through direct API manipulation (PATCH request) to bypass client-side validation, targeting the Block Editor's paragraph data structure within the JSON content field.

Impact

This vulnerability enables: - Persistent XSS - Malicious scripts execute whenever affected content is viewed - Session hijacking - Access to authentication tokens and cookies of users viewing the content - Administrative compromise - If administrators view infected content, their elevated privileges can be exploited - CSP bypass - Demonstrates ineffective security controls, potentially affecting other protections - Data exfiltration - Ability to steal sensitive information displayed in the application - Phishing attacks - Injection of convincing fake login forms or malicious redirects

Severity ?

5.5 (Medium)

Attackers can bypass Content Security Policy (CSP) restrictions by combining file uploads with iframe srcdoc attributes, resulting in persistent XSS execution.\n\n### Details\n\nThe vulnerability arises from insufficient sanitization in the Block Editor interface when processing JSON content containing HTML elements. The attack requires two permissions:\n- `upload files` - To upload malicious JavaScript files\n- `edit item` - To create or modify content with the Block Editor\n\n**Attack Vector:**\n\n1. **JavaScript File Upload**: Attackers upload a malicious JavaScript file via the files endpoint, obtaining a file ID accessible through the assets directory\n\n2. **Block Editor Exploitation**: Using a JSON field with Block Editor interface, attackers inject raw HTML containing an iframe with srcdoc attribute that references the uploaded file\n\n3. **CSP Bypass**: The iframe srcdoc technique circumvents existing CSP protections by creating a new document context that loads the uploaded script\n\nThe payload is injected through direct API manipulation (PATCH request) to bypass client-side validation, targeting the Block Editor\u0027s paragraph data structure within the JSON content field.\n\n### Impact\n\nThis vulnerability enables:\n- **Persistent XSS** - Malicious scripts execute whenever affected content is viewed\n- **Session hijacking** - Access to authentication tokens and cookies of users viewing the content\n- **Administrative compromise** - If administrators view infected content, their elevated privileges can be exploited\n- **CSP bypass** - Demonstrates ineffective security controls, potentially affecting other protections\n- **Data exfiltration** - Ability to steal sensitive information displayed in the application\n- **Phishing attacks** - Injection of convincing fake login forms or malicious redirects",
