What the vulnerability does
The MapSVG plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 8.14.0. This is due to insufficient input sanitization and output escaping on user supplied attributes within the map options. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
MapSVG versions up to 8.14.0 contain a stored cross-site scripting (XSS) vulnerability that allows authenticated users with low privileges to inject malicious scripts. The vulnerability has changed scope, meaning injected code can affect other users and site functionality beyond the vulnerable component. An attacker needs a low-privilege account to exploit this flaw.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect site functionality.
Potential impact on your site
Other site users may have their sessions compromised or see malicious content; site functionality may be altered.
Conditions required to exploit
Attacker must have a low-privilege authenticated account; no user interaction required.
