Description

The ARforms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'password' Field Values in all versions up to, and including, 7.2.1 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.

  "executiveSummary": "The ARforms plugin for WordPress suffers from a Stored Cross-Site Scripting (XSS) vulnerability affecting all versions up to, and including, 7.2.1. The security flaw stems from insufficient input sanitization and output escaping applied to the 'password' field values processed by the application.\nThis vulnerability enables unauthenticated threat actors to inject arbitrary web scripts, including malicious JavaScript, into vulnerable application pages. When legitimate users access the injected pages, the payload executes within the context of their browser session, leading to potential session hijacking, credential theft, or unauthorized actions performed on behalf of the victim.\nThe risk implication is high, as exploitation requires zero authentication and leverages public-facing form submission mechanisms to persist malicious scripts within the application data storage. Remediation requires updating the ARforms plugin to a patched version beyond 7.2.1 or applying strict input validation and contextual output escaping on all user-supplied input vectors associated with form fields.",
  "technicalDetails": "The vulnerability resides in the input handling and output rendering mechanisms of the ARforms plugin for WordPress in versions up to, and including, 7.2.1. Specifically, the component responsible for processing 'password' field values fails to adequately sanitize input data prior to database persistence and subsequently fails to properly encode output when rendering the data back to the browser.\nThe root cause is a lack of rigorous input sanitization combined with the absence of proper output escaping. In a standard exploitation scenario, an unauthenticated attacker interacts with a form generated by the ARforms plugin. By supplying a crafted payload containing malicious JavaScript within the 'password' field value during submission, the attacker bypasses the weak validation checks implemented by the plugin.\nThe attack flow proceeds as follows: First, the unauthenticated attacker crafts an HTTP request containing the malicious script payload destined for the vulnerable 'password' input field. Second, the ARforms plugin accepts the input and writes it directly to the database or internal data structures without stripping or neutralizing executable HTML and JavaScript tags. Third, when an administrator or another privileged user navigates to the administrative interface or page where the stored form submission data is displayed, the application reflects the unescaped payload back into the Hypertext Transfer Protocol response.\nFinally, the victim's browser parses the HTTP response, interprets the injected payload as legitimate executable script code, and executes it within the security context of the victim's session. Because this vulnerability involves Stored XSS, the payload persists across multiple HTTP requests until the malicious record is removed or sanitized. Network exposure is broad, as form submission endpoints are typically accessible to any unauthenticated visitor over the network via standard HTTP/HTTPS protocols."
