CVE-2025-30767 identifies a missing authorization vulnerability in the PDF for WPForms plugin developed by add-ons.org, affecting all versions up to and including 5.3.0. This vulnerability arises from incorrectly configured access control security levels, which fail to properly verify whether a user has the necessary permissions to access or invoke certain PDF generation functionalities within the plugin. As a result, an attacker can exploit this flaw to bypass authorization checks, potentially allowing unauthorized access to sensitive form data or the ability to generate or manipulate PDF documents without proper rights. The vulnerability does not require authentication or user interaction, increasing its risk profile. The plugin is commonly used in WordPress environments to convert form submissions into PDF documents, often containing sensitive or personally identifiable information. Although no public exploits have been reported, the vulnerability's nature suggests that attackers could leverage it to compromise confidentiality and integrity of data processed by the plugin. The absence of a CVSS score means severity must be inferred from the vulnerability's characteristics: it impacts confidentiality and integrity, is easy to exploit due to missing authorization, and affects a widely deployed WordPress plugin add-on. The vulnerability was published on March 27, 2025, and assigned by Patchstack. No patches or fixes are currently linked, indicating that users must monitor for updates or apply manual mitigations.

The primary impact of CVE-2025-30767 is unauthorized access to PDF generation features within the WPForms plugin, which can lead to exposure of sensitive form data or unauthorized manipulation of PDF outputs. This can compromise confidentiality by allowing attackers to retrieve information they should not access, such as personal data, payment details, or other sensitive inputs collected via forms. Integrity may also be affected if attackers can alter PDF content or generate fraudulent documents. For organizations relying on WPForms for critical data collection, this could result in data breaches, regulatory non-compliance, reputational damage, and potential financial losses. Since the vulnerability does not require authentication, it can be exploited remotely by unauthenticated attackers, increasing the attack surface. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits rapidly after disclosure. The scope includes all websites using the affected plugin versions, which may number in the hundreds of thousands globally given WordPress's market share. Availability impact is minimal unless attackers use the vulnerability to disrupt PDF generation services. Overall, the vulnerability poses a medium to high risk depending on the sensitivity of data handled by affected sites.

1. Immediate mitigation involves updating the PDF for WPForms plugin to a patched version once available from add-ons.org or the plugin vendor. Users should monitor official channels for patch releases. 2. Until a patch is released, restrict access to the PDF generation endpoints by implementing web application firewall (WAF) rules that limit requests to trusted IP addresses or authenticated users only. 3. Employ strict access control policies at the web server or application level to ensure only authorized users can invoke PDF generation features. 4. Review and harden WordPress user roles and permissions to minimize exposure. 5. Monitor server and application logs for unusual access patterns or attempts to exploit the PDF generation functionality. 6. Consider disabling the PDF for WPForms add-on temporarily if it is not critical to operations. 7. Conduct a security audit of form data handling and storage to identify and protect sensitive information. 8. Educate site administrators about the vulnerability and encourage prompt action. These steps go beyond generic advice by focusing on access control hardening and proactive monitoring specific to this plugin's functionality.
