CVE-2022-4997 in Jet Form Builder Stripe Gateway Plugin
Summary
by MITRE • 09/23/2026
The jet-form-builder-stripe-gateway WordPress plugin before 1.1.0 does not sanitise and escape a payment token before using it in a SQL statement, allowing unauthenticated users to extract arbitrary data from the database, including password hashes.

The vulnerability identified in JetFormBuilder Stripe Gateway versions prior to 1.1.0 represents a critical security flaw rooted in improper input validation and output encoding practices within the WordPress plugin ecosystem. This specific issue is classified under CWE-89, commonly known as SQL Injection, which occurs when an application includes user-supplied data in a database query without proper sanitization or escaping. In this context, the payment token, which serves as a unique identifier for Stripe transactions and customer records, was accepted directly from unauthenticated HTTP requests and inserted into a Structured Query Language statement used to retrieve transaction details. Because the plugin failed to apply parameterized queries or escape special characters such as single quotes, backslashes, or hexadecimal values, an attacker could manipulate the input string to alter the logic of the SQL command executed by the database management system.
The operational impact of this vulnerability is severe due to its unauthenticated nature, meaning that any external actor on the internet can exploit it without needing valid credentials for the WordPress site. By crafting malicious HTTP requests containing specially crafted payment tokens, an attacker can perform blind or error-based SQL injection attacks to extract sensitive information stored in the database. This includes not only transactional data but also administrative user details such as usernames and password hashes. The exposure of password hashes is particularly dangerous because these values are often used for offline brute-force cracking attempts. If weak hashing algorithms like MD5 or un-salted SHA1 were employed, or if users reused passwords across other services, the compromise could lead to full account takeover and lateral movement within the organization's infrastructure.
From a threat intelligence perspective, this vulnerability aligns with MITRE ATT&CK technique T1078, Valid Accounts, as it facilitates unauthorized access through credential theft, and T1564, Hidden Files and Directories, if used for data exfiltration via out-of-band channels or error-based extraction. The attack vector is typically classified under Network Attack Pathways where the initial foothold is gained remotely over HTTP/HTTPS services exposed to the public internet. WordPress plugins are frequent targets because they often extend core functionality with custom database interactions that may not adhere strictly to security best practices during development and code review processes.
Mitigation strategies for this vulnerability involve immediate remediation through software updates or manual code intervention if updating is not feasible in a legacy environment. The primary fix requires upgrading the JetFormBuilder Stripe Gateway plugin to version 1.1.0 or later, where the developers have implemented proper input sanitization and output escaping mechanisms. Specifically, the use of WordPress database abstraction methods such as $wpdb->prepare() ensures that all variables are properly escaped before being incorporated into SQL queries, thereby neutralizing injection attempts. Additionally, implementing Web Application Firewall rules can provide a layer of defense by detecting and blocking common SQL injection patterns in HTTP request parameters. For organizations managing multiple plugins, it is advisable to conduct regular security audits focusing on database interaction code paths and enforce strict coding standards that mandate parameterized queries for all dynamic data inputs.
