Vulnerability AssessmentAI

Risk Assessment The CVSS v3.1 score of 6.4 (Medium) reflects the vulnerability's moderate risk profile: network-accessible (AV:N), low attack complexity (AC:L), but requiring low-privilege authenticated access (PR:L) and no user interaction beyond the initial injection (UI:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated WordPress contributor with malicious intent (or a compromised contributor account) creates a new page or edits an existing page and inserts a Progress Bar shortcode with a malicious attribute such as [plus_progress_bar attribute='" onmouseover="alert(String.fromCharCode(88,83,83))"']. When administrators or other site users visit this page, the injected JavaScript executes in their browser context, potentially stealing their session cookies, WordPress nonce tokens, or redirecting them to a credential harvesting site. …
Remediation Update The Plus Addons for Elementor plugin immediately to the first patched version released after 6.4.9. … Detailed patch versions, workarounds, and compensating controls in full report.
