Overview
CVE-2025-13696 is a security vulnerability affecting the Zigaform plugin for WordPress. This vulnerability allows unauthenticated attackers to potentially access sensitive information submitted through forms created with the plugin. Specifically, the flaw stems from a lack of authorization checks on an AJAX endpoint, enabling attackers to retrieve form submission data by enumerating form IDs.
Technical Details
The vulnerability resides in how the Zigaform plugin handles requests to the rocket_front_payment_seesummary AJAX action. Versions up to and including 7.6.5 do not implement proper authentication or authorization checks before retrieving and displaying form submission data. An attacker can exploit this by sending requests to this endpoint while incrementing the form_r_id parameter. By sequentially guessing these IDs, they can potentially access submissions from various forms, including those containing personal information, payment details, and other confidential data.
The vulnerable code is located within the uiform-fb-controller-frontend.php file. While a fix was applied in later versions, the unprotected endpoint in affected versions allows for unauthorized data retrieval.
CVSS Analysis
- Severity: MEDIUM
- CVSS Score: 5.3
- CVSS Vector: AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N (Based on typical calculation, exact vector might vary depending on calculator used)
The CVSS score reflects the ease of exploitation (no authentication required) and the potential for confidentiality impact (exposure of sensitive data). Although the integrity and availability are not directly affected, the potential for data breach makes this a significant security concern.
Possible Impact
Successful exploitation of CVE-2025-13696 can lead to:
- Data breaches: Exposure of personally identifiable information (PII), such as names, addresses, email addresses, and phone numbers.
- Payment information theft: Compromise of credit card details or other payment information submitted through forms.
- Reputational damage: Loss of customer trust and negative impact on the website’s reputation.
- Compliance violations: Potential violations of data privacy regulations, such as GDPR or CCPA, resulting in fines and legal repercussions.
Mitigation and Patch Steps
- Update the Zigaform plugin: The most effective solution is to update to the latest version of the Zigaform plugin. Versions newer than 7.6.5 contain the necessary security fix.
- Verify Plugin Version: Double check the installed version of Zigaform on your WordPress site to confirm that the update was successful.
- Web Application Firewall (WAF) Rules: Implement WAF rules to detect and block suspicious requests targeting the vulnerable endpoint. While this can offer a degree of protection, updating the plugin is strongly recommended.
- Review Form Submissions: Investigate your form submissions for any unusual activity, such as large numbers of requests for specific form IDs.
