CVE-2025-3779

Personizely <= 0.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via widgetId Parameter

Published May 3, 2025 CVSS 3.1 · 6.4 Medium EPSS < 1% KEV · Not listed

Description

The Personizely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘widgetId’ parameter in all versions up to, and including, 0.10 due to insufficient input sanitization and output escaping. 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.

Analysis

Technical impact

This vulnerability arises due to inadequate sanitization of the widgetId parameter in the Personizely plugin, enabling authenticated users with Contributor privileges to store malicious scripts. When a page containing the injected widgetId is viewed, the browser executes the embedded script, which may lead to unintended behavior. It is identified as a CWE‑79 type problem.

Affected Systems

WordPress installations using the Personizely A/B Testing, Personalization, Popups & CRO plugin up to and including version 0.10 are vulnerable. The vendor is personizely, and the affected product is the Personizely plugin.

Risk and Exploitability

The CVSS score is 6.4, indicating moderate severity, while the EPSS score of less than 1% suggests a low probability of exploitation at present and the vulnerability is not listed in the CISA KEV catalog. An attacker would need to be an authenticated Contributor or higher and would exploit the flaw by submitting a malicious widgetId value through the plugin’s interface; execution is triggered when any site visitor loads the affected page.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
