Exploitation Conditions

The plugin must be installed and active on the target WordPress site (any version ≤1.15.46). The attacker requires no credentials of their own (PR:N per CVSS). The victim must be an authenticated WordPress user with access to the plugin's Submissions admin page - typically a site administrator or editor - and must click or follow a crafted URL containing the malicious bulk_action payload (UI:R). No special plugin configuration is required beyond active installation. Limiting factors: the social-engineering requirement (UI:R) prevents automated mass exploitation; the target audience is narrowed to users with admin-area access, not arbitrary site visitors.

Impact

The CVSS 6.1 score is appropriate and reflects genuine constraints: UI:R means the attacker cannot exploit this without social engineering, and the realistic target is an authenticated WordPress user with access to the plugin's Submissions admin page - typically an administrator or editor. The C:L/I:L ratings correctly bound the impact to limited cookie theft or session-scoped admin actions rather than full server compromise. No public exploit code, CISA KEV listing, or EPSS score is available from the provided intelligence, suggesting no observed widespread exploitation. Real-world risk is moderate for sites running the plugin actively: form management plugins are commonly deployed and the admin Submissions page is a plausible phishing target in spear-phishing campaigns against site owners. The attack requires no attacker authentication (PR:N confirmed by CVSS), but delivery friction (UI:R) substantially limits opportunistic exploitation.

Exploit ScenarioDerived

An attacker identifies a WordPress site running Form Maker by 10Web ≤1.15.46 and crafts a URL targeting the plugin's Submissions admin page with a JavaScript payload embedded in the bulk_action parameter. The attacker delivers this URL to a site administrator via phishing email; when the admin clicks the link while authenticated, the script executes in their browser, exfiltrating session cookies or silently creating a new admin account. No public proof-of-concept code was identified at time of analysis.

AnalysisAIv1 – Sep 10, 2026

Reflected XSS in the Form Maker by 10Web WordPress plugin (all versions ≤1.15.46) allows unauthenticated attackers to inject arbitrary JavaScript into WordPress admin pages via the unsanitized bulk_action parameter in the Submissions controller. Successful exploitation requires social-engineering an authenticated WordPress admin into clicking a crafted link, enabling session hijacking or unauthorized admin actions in the victim's browser context. No public exploit code or CISA KEV listing has been identified; version 1.15.47 resolves the issue per confirmed WordPress SVN changesets.

RemediationAI

Upgrade the Form Maker by 10Web plugin to version 1.15.47 or later; the fix is confirmed by WordPress SVN changesets at https://plugins.trac.wordpress.org/changeset?reponame=&new=3686568%40form-maker%2Ftags%2F1.15.47&old=3652521%40form-maker%2Ftags%2F1.15.46 and https://plugins.trac.wordpress.org/changeset/3686567/form-maker/trunk/admin/controllers/Submissions_fm.php. Until the upgrade is applied, administrators can restrict access to the WordPress admin area (wp-admin) by IP allowlist at the web server or WAF layer, which prevents an unauthenticated attacker from delivering a payload to a victim who cannot be reached through admin-facing URLs. Note that IP restriction may impact legitimate remote admins. Disabling the plugin entirely is a viable interim control if Submissions management is not actively required.

Technical ContextAI · show details

The vulnerability resides in two files of the plugin's admin layer: admin/controllers/Submissions_fm.php (lines 80 and 127) and the shared utility framework/WDW_FM_Library.php (line 938), all confirmed present in the SVN tag for version 1.15.46. The bulk_action GET/POST parameter is reflected into HTML output without sufficient input sanitization or output escaping, satisfying CWE-79 (Improper Neutralization of Input During Web Page Generation). The CVSS scope change (S:C) reflects that injected script executes in the browser's privileged WordPress admin context, potentially crossing the boundary between the plugin's own page and the broader WordPress admin session. The affected CPE is cpe:2.3:a:10web:form_maker_by_10web_-_mobile-friendly_drag_&_drop_contact_form_builder:*:*:*:*:*:*:*:*.

DescriptionCVE.org

The Form Maker by 10Web - Mobile-Friendly Drag & Drop Contact Form Builder plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the bulk_action parameter in all versions up to, and including, 1.15.46 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
