CVE-2025-9207 Overview
CVE-2025-9207 affects the TI WooCommerce Wishlist plugin for WordPress in all versions up to and including 2.10.0. The plugin accepts hidden form fields without validating or restricting the values that users can submit. These values are later rendered in wishlist items, enabling unauthenticated attackers to inject arbitrary HTML content. The flaw is categorized as improper input validation [CWE-20] and requires no authentication or user interaction to exploit over the network.
Critical Impact
Unauthenticated attackers can inject arbitrary HTML into wishlist items, enabling content spoofing, phishing lures, and defacement of storefront pages that render wishlist data.
Affected Products
- TI WooCommerce Wishlist plugin for WordPress — all versions up to and including 2.10.0
- WordPress sites running WooCommerce with the vulnerable plugin installed
- Storefronts that publicly display wishlist items generated through the plugin
Discovery Timeline
- 2025-12-13 - CVE-2025-9207 published to the National Vulnerability Database (NVD)

Technical Details for CVE-2025-9207
Vulnerability Analysis
The TI WooCommerce Wishlist plugin exposes hidden form fields that accept user-supplied input during wishlist creation and item addition. The plugin fails to validate the type, length, or content of these hidden fields before persisting them. When wishlist items are later rendered in the storefront, the stored values are output into HTML context without adequate sanitization. This allows an unauthenticated attacker to submit crafted payloads that produce arbitrary HTML markup in the rendered output. The impact is limited to integrity of displayed content — no confidentiality or availability impact is reported — but attackers can leverage the flaw to insert misleading UI elements, fake login prompts, or malicious anchors.
Root Cause
The root cause is missing input validation on hidden fields processed by the wishlist handler. Code paths in includes/wishlist.class.php (referenced at lines 326 and 544 in the plugin trunk) accept and store attacker-controlled values without enforcing an allowlist of expected characters or field structures. Sanitization functions such as wp_kses, sanitize_text_field, or context-aware escaping on output are not applied to these fields.
Attack Vector
An unauthenticated remote attacker sends HTTP requests to the WordPress site that add items to a wishlist while supplying malicious content in hidden fields. The plugin stores the values and later renders them into HTML pages served to visitors. Because the attack is network-based with low complexity and requires no privileges or user interaction, exploitation can be automated against any exposed storefront running a vulnerable version.
No verified public exploit code is available. Technical details are documented in the WordPress plugin source at wishlist.class.php line 326, the related handler at line 544, and the Wordfence Vulnerability Report.
Detection Methods for CVE-2025-9207
Indicators of Compromise
- Wishlist database entries containing unexpected HTML tags such as <a>, <img>, <iframe>, or <form> elements in fields that should hold plain text
- HTTP POST requests to wishlist endpoints with hidden field parameters containing angle brackets or HTML entities
- Storefront pages rendering wishlist content that includes external links or images not added by legitimate users
Detection Strategies
- Query the WordPress database for wishlist rows where stored values contain HTML tag characters and review them for injected markup
- Inspect web server access logs for anonymous POST requests to wp-admin/admin-ajax.php or wishlist REST endpoints with suspicious payload patterns
- Compare the installed plugin version against the fixed release in the WordPress changeset 3399224
Monitoring Recommendations
- Monitor WooCommerce wishlist tables for INSERT and UPDATE operations that include HTML entities or tag characters
- Alert on outbound links appearing in rendered wishlist pages that reference untrusted external domains
- Track spikes in unauthenticated wishlist creation requests from single IP addresses or user-agent strings
How to Mitigate CVE-2025-9207
Immediate Actions Required
- Update the TI WooCommerce Wishlist plugin to a version later than 2.10.0 that includes the fix referenced in WordPress changeset 3399224
- Audit existing wishlist data for HTML content and purge injected entries before rendering to visitors
- Restrict anonymous wishlist creation where the business flow permits, requiring authenticated sessions instead
Patch Information
The vendor addressed the flaw in the plugin release that follows version 2.10.0. Refer to the WordPress plugin changeset and the Wordfence Vulnerability Report for advisory details and version guidance.
Workarounds
- Deploy a web application firewall (WAF) rule that blocks HTTP requests to wishlist endpoints containing HTML tag characters in hidden field parameters
- Temporarily disable public rendering of wishlist items until the plugin is updated
- Apply output-side filtering with wp_kses_post on wishlist item fields in a custom theme or child-theme template as a stopgap
# Example WP-CLI commands to identify and update the vulnerable plugin
wp plugin get ti-woocommerce-wishlist --field=version
