Lifecycle Timeline
1DescriptionCVE.org
A stored Cross-Site Scripting (XSS) vulnerability in the file upload functionality of the Media Manager in TastyIgniter v4.3.0, caused by insufficient validation and sanitization of SVG files. An authenticated user with low privileges can upload a malicious SVG file containing JavaScript code. When an administrator views that file, the code executes in the context of their browser. By chaining this vulnerability with a Cross-Site Request Forgery (CSRF) attack, an attacker can extract the administrator’s CSRF token and perform unauthorized actions-such as modifying credentials-thereby gaining full control of the administrative account.
AnalysisAI
Stored cross-site scripting in TastyIgniter's Media Manager allows low-privileged authenticated users to execute arbitrary JavaScript when an administrator views a malicious SVG file. Chaining with CSRF enables an attacker to steal the admin's CSRF token and take full control of the administrative account. No public exploit or active exploitation has been identified; EPSS is low (0.23%), and the vulnerability is rated CVSS 6.3 in CVSS 4.0.
