Vulnerability mechanics

Root cause

"Missing sanitization and escaping of plugin settings allows stored cross-site scripting."

Attack vector

An attacker with editor-level privileges (high privilege user) can inject malicious JavaScript into plugin settings that are not sanitized or escaped [ref_id=1]. When an administrator or other user views the affected settings page, the stored script executes in their browser. This is a Stored Cross-Site Scripting (XSS) attack [CWE-79] [ref_id=1]. The attack requires authenticated access with at least editor capabilities.
