Attack-Flow Graph

Executive Summary

This vulnerability is a stored Cross-site Scripting (XSS) issue in ClipBucket v5 versions 5.5.2-#146 and below. An authenticated regular user can upload a photo with a malicious Photo Title containing HTML or JavaScript code. Although the malicious code does not execute in the user-facing photo gallery or detail pages, it is rendered unsafely in the Admin → Manage Photos section, causing the JavaScript to execute in the administrator's browser. This can lead to unauthorized actions or data exposure in the admin interface. The issue is fixed in version 5.5.2-#147.

Impact Analysis

This vulnerability can impact you by allowing an attacker with regular user access to execute malicious JavaScript code in the administrator's browser when they view the Manage Photos section. This can lead to unauthorized actions performed with admin privileges, theft of sensitive information, session hijacking, or other malicious activities affecting the security and integrity of the platform.

Mitigation Strategies

Upgrade ClipBucket to version 5.5.2-#147 or later, where the vulnerability is fixed. Additionally, restrict access to the Admin → Manage Photos section to trusted administrators only and avoid opening suspicious photo titles containing HTML/JavaScript code until the upgrade is applied.
