Urgent: Authenticated Contributor DOM-based Stored XSS in “Animation Addons for Elementor” (<= 2.6.7) — What WordPress Site Owners Must Do Now

Publié : 9 June, 2026
Gravité : CVSS 6.5 (Medium) — CVE-2025-8444
Logiciel affecté : Animation Addons for Elementor (GSAP Motion Elementor Addons & Website Templates) — versions ≤ 2.6.7
Privilège requis : Contributeur (authentifié)
Type d'exploitation : DOM-based stored Cross-Site Scripting (XSS) — stored payload executed in victim’s browser when the stored content is rendered or interacted with

From the perspective of a Hong Kong security expert: this advisory is practical and action-oriented. The vulnerability allows an authenticated Contributor to persist JavaScript payloads in plugin-managed data. When certain pages or admin panels render or interact with that stored content, the payload may execute in the browser of other users — including Editors and Administrators. Potential consequences include credential theft, session hijacking, site defacement, persistent backdoors, or privileged account compromise.

Résumé exécutif

• Que s'est-il passé : A Contributor can persist JavaScript into site data that is later read by client-side plugin code and injected unsafely into the DOM, causing execution in visitors’ browsers.
• Qui est à risque : Any site running the vulnerable plugin versions (≤ 2.6.7) that allows Contributors or similar low-privileged accounts to create templates, animation settings, or rich content.
• Action immédiate : Restrict Contributor accounts, audit stored content for script-like payloads, apply containment controls (disable plugin if necessary, use WAF/virtual patching where available, enforce CSP), and plan a code fix or upgrade.
• À long terme : Fix plugin code with proper input validation and safe output encoding, adopt least privilege practices, enforce 2FA, logging and monitoring, and ensure timely patching procedures.

What is DOM-based stored XSS? Why it matters

Cross-Site Scripting (XSS) typically appears in three forms:

• XSS stocké (persistant) — attacker-supplied input is stored on the server (database, postmeta, plugin settings) and later served to users without safe encoding.
• XSS réfléchi — payloads reflected in server responses from URL parameters or form inputs.
• DOM-based XSS — vulnerability arises in the browser when client-side JavaScript processes untrusted data and inserts it into the DOM unsafely.

This advisory concerns DOM-based stored XSS: an attacker stores a payload (e.g., in a template, animation configuration, or plugin field). When client-side plugin code later reads that value and injects it into the page DOM using unsafe APIs (innerHTML, eval, etc.), the script executes in the victim’s browser.

Risques clés :

• Execution in the context of any user viewing the affected page — admin sessions are high-value targets.
• Persistence — the payload remains until removed, allowing repeated exploitation.
• Server-side filters may be bypassed because the final injection occurs client-side.

Typical attack flow (high-level)

1. Attacker obtains or registers a Contributor account (or similar low-privileged role).
2. Using plugin UI available to that role, attacker saves crafted data (animation settings, template metadata, custom fields) containing a JavaScript payload.
3. Data is stored in database tables (posts, postmeta, options, or plugin tables).
4. When another user (Editor, Admin or visitor) opens a page or admin screen, plugin JavaScript reads the stored value and injects it into the DOM unsafely, triggering execution.
5. Payload consequences depend on target: session theft, account takeover, backdoors, content modification, or malware delivery.

Real impacts seen with similar vulnerabilities

• Administrative takeover by exfiltrating session cookies or auth tokens.
• Silent installation of backdoors or malicious plugins when an admin’s browser executes attacker code.
• SEO and reputational damage from injected spam content.
• Persistence through postmeta or template JSON that survives updates and backups.
• Theft of customer/payment data on pages where sensitive interactions occur.

Even with a medium CVSS rating, urgency is warranted because the attack chain requires only low privileges to establish persistence and can later affect high-value accounts.

Comment déterminer rapidement si vous êtes affecté

1. 12. WP‑Admin → Plugins → Plugins installés → recherchez "GMap Generator (Venturit)". Si la version ≤ 1.1, vous êtes affecté.
   • Admin > Plugins: check for “Animation Addons for Elementor” or related GSAP/animation addons.
   • If version is ≤ 2.6.7, treat as vulnerable.
2. Inspect user roles:
   • Users > All Users: look for Contributor accounts and recent additions or changes.
   • Check whether Contributors can create templates, animations, or upload content.
3. Search database for suspicious script tags or JSON:

   Examples (adjust prefixes as needed):

   wp db query "SELECT ID, post_title, post_type FROM wp_posts WHERE post_content LIKE '%

   wp db query "SELECT post_id, meta_key, meta_value FROM wp_postmeta WHERE meta_value LIKE '%

4. Check logs for unusual admin actions, unexpected POSTs to admin-ajax.php, or REST endpoints related to the plugin.
5. Examine plugin UI: templates, animation libraries, and user-editable fields that accept HTML, JSON, or script-like input.

// Prefer:
element.textContent = userProvidedString;

// Avoid:
element.innerHTML = userProvidedHtml;
