MITRE ATT&CK
2 techniques across 2 tactics: Initial Access, Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires that the plugin's chatbot module is active AND at least one chatbot is configured; without the chatbot enabled the storage path is not reachable, so this is not exploitable against a default/unconfigured install. Given that precondition, no authentication is required (CVSS PR:N): the attacker stores the payload via three unauthenticated REST calls to the chatbot endpoints. The limiting factor for impact is that execution occurs only when a logged-in administrator opens the wp-admin dashboard (wp-admin/index.php), where the dashboard widget's auto-poll renders the unescaped 'name' value - so the ultimate payload fires in an authenticated admin browser context rather than on public pages. |
| Impact | This is a stored DOM-based XSS (CWE-79) in the WordPress 'AI Marketing Expert' plugin, versions ≤1.2.8. The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N, base 7.2) describes a network-reachable, low-complexity, unauthenticated flaw with a changed scope - consistent with the description, since an unauthenticated attacker stores a payload that later executes in a logged-in administrator's wp-admin session (a different security authority, hence S:C). No EPSS score was supplied and the CVE is NOT in CISA KEV, so there is no confirmed active exploitation. No working exploit code is referenced either: the provided links are the Wordfence advisory and WordPress trac source-code lines used for patch/root-cause analysis, not a published PoC. The vuln.today priority is 'this_week' rather than act_now/emergency, which aligns with a serious-but-not-emergency posture. The practical risk is tempered by a real precondition - the chatbot module must be active with at least one configured bot - so this is not a default-configuration drive-by; it affects deployments that have enabled the chatbot feature. Net: a genuine, remotely-storable XSS worth patching this cycle, but the 7.2 base score overstates urgency given no KEV, no supplied EPSS, no public exploit, and a non-default feature prerequisite. |
| Exploit ScenarioDerived | An unauthenticated attacker sends three crafted REST requests to a site running the plugin with the chatbot module enabled and at least one bot configured, storing a malicious script in the 'name' parameter. The plugin's dashboard-widget JavaScript then auto-polls and renders the attacker-controlled value without proper escaping, so the script executes in the browser of any administrator who opens wp-admin/index.php. No public exploit code is referenced at time of analysis. |

Alert meAnalysisAIv1 – Oct 28, 2026
Stored DOM-based cross-site scripting in the WordPress plugin AI Marketing Expert (all versions up to and including 1.2.8) allows unauthenticated attackers to persist arbitrary JavaScript through the chatbot's unescaped 'name' parameter and have it execute in an administrator's browser. The storage path is reachable only when the chatbot module is active with at least one bot configured: the attacker writes the payload via three unauthenticated REST calls, and the dashboard widget's auto-poll then renders it when a logged-in admin opens wp-admin/index.php. Impact is bounded by that admin-only execution context (CVSS 7.2, scope-changed, low confidentiality/integrity), and no public exploit code was identified at time of analysis; a fixed release is available as version 1.2.9.
RemediationAI
Update the plugin to version 1.2.9, the fixed release published in the WordPress.org plugin repository (tag reference https://plugins.trac.wordpress.org/browser/ai-marketing-expert/tags/1.2.9), and confirm the installed version under Plugins in wp-admin. If updating immediately is not possible, disable the chatbot module or remove all configured bots, since the vulnerability's storage path is only reachable when the chatbot is active with at least one bot configured; the trade-off is that all chatbot functionality goes offline for the site. Restricting or blocking unauthenticated access to the plugin's chatbot REST routes at the web server or WAF layer can also interrupt the three-call storage chain, at the risk of breaking legitimate front-end chatbot traffic. Administrators should also avoid leaving idle wp-admin dashboard sessions open in browsers until the update is applied, as execution occurs when the dashboard widget polls. Full technical detail is in the Wordfence advisory linked above.

Technical ContextAI · show details
The flaw is CWE-79 cross-site scripting with a DOM-based delivery chain in a PHP/WordPress plugin. The chatbot exposes unauthenticated REST endpoints (modules/chatbot/class-chatbot-rest-controller.php) whose public controller (class-public-controller.php) accepts and stores the 'name' value without adequate sanitization; the stored value is later pulled by the admin dashboard widget (includes/admin/class-dashboard-widget.php) and injected into the DOM by dashboard-widget.js at the sink locations referenced in the advisory, without output escaping. Because the sink is client-side JavaScript rendering rather than server-side HTML reflection, the payload executes as a DOM XSS in the wp-admin context once the widget's auto-poll refreshes. The scope change (S:C) in the CVSS vector reflects that code executes in the privileged administrator dashboard origin rather than the attacker's own context. Exploitation is conditional: the chatbot module must be enabled and at least one bot configured, otherwise the storage endpoints are unreachable and the plugin is not exploitable in a default or unconfigured install.

DescriptionCVE.org
The AI Marketing Expert - AI Email Marketing, AI Content Generator, SEO Analyzer, AI Workflow Automation, Social Media & Ai Chatbot plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'name' parameter in all versions up to, and including, 1.2.8 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. Exploitation requires only that the chatbot module is active with at least one configured bot; the attacker stores the payload via three unauthenticated REST calls, and the JavaScript widget auto-poll then delivers it to any administrator who opens wp-admin/index.php.
Executive ViewAI
The AI Marketing Expert WordPress plugin (versions up to 1.2.8) contains a stored cross-site scripting vulnerability that could let an unauthenticated attacker inject malicious JavaScript into an administrator's browser session. This puts WordPress site integrity and confidentiality at risk, as an attacker could perform administrative actions on behalf of a compromised admin. Leadership should prioritize patching because the plugin is widely used and the attack requires minimal effort once a chatbot is configured.
Apply vendor patch: upgrade to AI Marketing Expert version 1.2.9. If patching is delayed, disable the chatbot module or ensure no bots are configured to prevent exploitation.
