The User Profile Builder - Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'email' parameter in all versions up to, and including, 4.0.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload reaches administrators with the manage_options capability when they visit the Users > Unconfirmed Email Addresses list table and interact with row-action links, as the poisoned javascript: href is rendered verbatim into the page HTML by row_actions().
AnalysisAI
Stored XSS in the User Profile Builder WordPress plugin (all versions through 4.0.0) allows unauthenticated attackers to inject malicious JavaScript via the email parameter submitted during user registration. The payload persists in the unconfirmed email addresses database and executes in the browser of any administrator with manage_options capability who visits the Users > Unconfirmed Email Addresses list table and interacts with row-action links, because the row_actions() function renders the stored email value verbatim as a javascript: href. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Two conditions must be met for exploitation: first, the User Profile Builder plugin's email confirmation feature must be enabled and the site must allow unauthenticated user registration, so that attacker-controlled email values reach the unconfirmed addresses list; second, an administrator with the manage_options WordPress capability must visit the Users > Unconfirmed Email Addresses list table and interact with row-action links rendered by row_actions(). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) reflects a medium-severity stored XSS with scope change, appropriately capturing the admin-browser execution context. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
