What the vulnerability does
The Your Simple SVG Support plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 1.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
Explanation of Vulnerability in Simple Terms
Your Simple SVG Support versions 1.0.1 and earlier contain a cross-site scripting vulnerability. An attacker with low-level site access can inject malicious scripts that execute in other users' browsers, potentially compromising their accounts or stealing data. The vulnerability affects the entire site due to scope change, meaning impacts extend beyond the vulnerable component itself.
What an attacker can do
Inject malicious scripts that run in other users' browsers to steal data or compromise accounts.
Potential impact on your site
Authenticated attackers can execute JavaScript in other users' sessions, risking account takeover and data theft across your site.
Conditions required to exploit
Attacker needs low-level site access (e.g., contributor or subscriber role); no user interaction required.
