CVE-2025-6743 Overview
CVE-2025-6743 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Woodmart theme for WordPress. The flaw exists in the theme's multiple_markers attribute handler and stems from insufficient input sanitization and output escaping on user supplied attributes. Authenticated users with contributor-level access or higher can inject arbitrary web scripts into pages. The injected scripts execute in the browser of any visitor who loads the affected page. The vulnerability affects all Woodmart theme versions up to and including 8.2.3. The issue is tracked under CWE-79: Improper Neutralization of Input During Web Page Generation.
Critical Impact
Contributor-level attackers can persistently inject JavaScript that executes in the context of site visitors and administrators, enabling session theft, defacement, and privilege escalation via administrative actions.
Affected Products
- Xtemos Woodmart theme for WordPress, all versions up to and including 8.2.3
- WordPress sites using the Woodmart WooCommerce theme
- Sites permitting contributor-level or higher user registration with access to Woodmart shortcodes or elements

Technical Details for CVE-2025-6743
Vulnerability Analysis
The vulnerability resides in how the Woodmart theme processes the multiple_markers attribute. The theme accepts user-controlled input through this attribute but fails to sanitize the value on ingress and does not escape it on output. As a result, script payloads persist in the site database and render as executable JavaScript when pages are viewed.
Exploitation requires an authenticated account with contributor-level privileges or higher. Contributors can create draft posts and pages, which is sufficient to embed the malicious attribute. When an administrator previews the content or when the page is later published and visited, the payload executes in the visitor's browser session.
Stored XSS in a WordPress theme is particularly impactful because payloads can target administrator sessions to perform privileged actions such as creating new admin users, modifying theme files, or installing plugins.
Root Cause
The root cause is missing input sanitization and output escaping on the multiple_markers attribute. WordPress provides sanitization helpers such as sanitize_text_field() and escaping helpers such as esc_attr() and esc_html(), but the vulnerable code path does not apply these functions before rendering attribute data into the DOM.
Attack Vector
The attack proceeds over the network against an authenticated session. An attacker logs in with a contributor account, creates or edits content that leverages the Woodmart element or shortcode accepting multiple_markers, and inserts a JavaScript payload into the attribute value. When the crafted content is rendered, the payload executes in the browser of any user who views it, including administrators reviewing the submission. User interaction (viewing the page) is required for the payload to fire.
See the Wordfence Vulnerability Report for additional technical details on the affected attribute.
Detection Methods for CVE-2025-6743
Indicators of Compromise
- Post or page content containing multiple_markers attribute values with <script> tags, javascript: URIs, or event handlers such as onerror= and onload=.
- Newly created contributor or author accounts followed by draft submissions containing Woodmart shortcodes or elements.
- Unexpected administrator account creation, plugin installation, or theme file modification shortly after content review activity.
Detection Strategies
- Audit the wp_posts table for stored content referencing multiple_markers alongside HTML script constructs or encoded script payloads.
- Monitor WordPress application logs for content submissions from contributor accounts that include unusual HTML or JavaScript syntax in shortcode attributes.
- Deploy a web application firewall rule that inspects POST requests to /wp-admin/post.php and /wp-admin/admin-ajax.php for script-like tokens within Woodmart shortcode attributes.
Monitoring Recommendations
- Track the installed Woodmart theme version and alert when instances at or below 8.2.3 are detected.
- Alert on privilege changes, especially promotions from contributor or author to administrator, and on new administrator account creation.
- Log outbound requests from browsers rendering CMS pages to identify beaconing consistent with XSS payload execution.
How to Mitigate CVE-2025-6743
Immediate Actions Required
- Upgrade the Woodmart theme to a version later than 8.2.3 as soon as the vendor publishes a fixed release.
- Review and revoke unnecessary contributor, author, or editor accounts, particularly recently created ones.
- Scan existing posts and pages for stored payloads within multiple_markers and other Woodmart shortcode attributes and remove any suspicious content.
Patch Information
Refer to the vendor's product page on ThemeForest and the Wordfence Vulnerability Report for the latest patched version information. Apply the update through the WordPress theme updater or by replacing the theme files with the vendor-supplied package.
Workarounds
- Restrict user registration and remove contributor-level access for untrusted users until the theme is patched.
- Deploy a web application firewall with rules that block script tokens, event handlers, and javascript: URIs in shortcode attributes.
- Enforce a strict Content Security Policy (CSP) that disallows inline scripts to reduce the impact of successful injection.
# Content Security Policy header example to limit inline script execution
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'"
