CVE-2025-26913 Overview
CVE-2025-26913 is a DOM-Based Cross-Site Scripting (XSS) vulnerability in the webandprint AR For WordPress plugin (ar-for-wordpress). The flaw affects all plugin versions up to and including 7.7. It stems from improper neutralization of input during web page generation, classified under [CWE-79].
An authenticated attacker with low privileges can inject malicious script content that executes in the browser context of a victim who interacts with a crafted page. Successful exploitation requires user interaction and can compromise the confidentiality, integrity, and availability of data rendered in the affected scope.
Critical Impact
Attackers can execute arbitrary JavaScript in the context of a visiting user's browser session, enabling session token theft, forced browser actions, and defacement across the WordPress site.
Affected Products
- webandprint AR For WordPress plugin (ar-for-wordpress)
- All plugin versions from initial release through 7.7
- WordPress installations that render augmented reality content using the plugin

Technical Details for CVE-2025-26913
Vulnerability Analysis
The vulnerability is a DOM-Based XSS issue in the AR For WordPress plugin. DOM-Based XSS occurs when client-side JavaScript writes attacker-controlled data into the Document Object Model (DOM) without proper sanitization or encoding.
Unlike reflected or stored XSS, the injection payload never needs to be processed by the server. The malicious script is constructed and executed entirely within the victim's browser when the vulnerable client-side code parses the tainted input.
Exploitation requires the attacker to have at least low-level privileges on the target WordPress site and to convince a user to interact with a crafted request or page. The scope is changed, meaning the injected script can affect resources beyond the initial vulnerable component.
Root Cause
The root cause is improper neutralization of user-supplied input before it is written to the DOM by the plugin's client-side JavaScript. Input sources such as URL fragments, query parameters, or plugin configuration values reach a DOM sink such as innerHTML, document.write, or eval without encoding. Refer to the Patchstack XSS Vulnerability Advisory for the technical breakdown.
Attack Vector
An attacker with low privileges crafts input containing a JavaScript payload and delivers a malicious link to a victim. When the victim loads the page, the plugin's client-side code writes the tainted value into a DOM sink and the payload executes with the origin of the WordPress site.
The attacker can then read cookies not marked HttpOnly, capture form input, initiate authenticated requests, or redirect the victim to attacker-controlled infrastructure. Because scope is changed, the impact can extend to authenticated administrator sessions or other site contexts.
Detection Methods for CVE-2025-26913
Indicators of Compromise
- Requests to the WordPress site containing script-like payloads in URL parameters, fragments, or plugin-specific fields
- Unexpected outbound requests from user browsers to external domains after loading pages that render AR content
- WordPress user accounts performing actions outside their normal behavior, indicating session compromise
Detection Strategies
- Review web server access logs for URIs targeting ar-for-wordpress endpoints with encoded HTML or JavaScript payloads such as %3Cscript%3E or javascript: URIs
- Deploy a web application firewall (WAF) with signatures for common XSS payload patterns targeting WordPress plugins
- Perform authenticated dynamic application security testing (DAST) against pages rendered by the AR For WordPress plugin
Monitoring Recommendations
- Enable WordPress audit logging for plugin configuration changes and content updates by low-privileged users
- Monitor browser Content Security Policy (CSP) violation reports for script-src breaches on pages containing AR content
- Alert on anomalous session activity such as privilege changes or content modifications following an authenticated user's page visit
How to Mitigate CVE-2025-26913
Immediate Actions Required
- Inventory all WordPress sites and identify installations running the AR For WordPress plugin at version 7.7 or earlier
- Deactivate the plugin on affected sites until a fixed version is confirmed available from the vendor
- Rotate credentials and invalidate active sessions for any user who may have interacted with a suspicious link targeting the plugin
Patch Information
At the time of publication, the advisory covers versions through 7.7 with no fixed version explicitly documented in the CVE record. Consult the Patchstack XSS Vulnerability Advisory for the latest remediation guidance and monitor the plugin's WordPress.org page for updated releases.
Workarounds
- Remove or deactivate the ar-for-wordpress plugin until a patched release is available
- Enforce a strict Content Security Policy that disallows inline scripts and restricts script-src to trusted origins
- Restrict plugin configuration access to trusted administrators and audit existing low-privileged accounts for necessity
- Deploy a WAF rule set that filters XSS payloads on requests to plugin endpoints
