Speak to Experts

A vulnerability has been found in jiujiujia/victor123/wxw850227 jjjfood and jjjshop_food up to 20260103. This vulnerability affects unknown code of the file /index.php/api/product.category/index. Such manipulation of the argument latitude leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product is distributed under multiple different names. The vendor was contacted early about this disclosure but did not respond in any way.

The severity of this vulnerability is classified as low, with a CVSS score of 2.1. Despite the low severity, organizations should remain vigilant, as SQL injection vulnerabilities can be exploited by attackers to gain unauthorized access to sensitive data or systems.

Organizations should prioritize patching immediately. Although the exploit has been disclosed, there is currently no public exploit confirmed, which means defenders have a window of opportunity to mitigate the risk.

Risk to organizations includes potential unauthorized access to sensitive information through successful SQL injection attacks. Even with a low severity rating, the implications are significant, especially if sensitive customer data is involved.

Vulnerability Details

The vulnerability description indicates a SQL injection issue that can be exploited by manipulating the latitude argument in the affected API endpoint. The vulnerability was published on January 11, 2026, and is currently in a deferred status, indicating that a formal resolution has not yet been issued.

Technical Analysis

The root cause of this vulnerability is due to improper input validation in the API endpoint, which allows attackers to execute arbitrary SQL queries. The attack vector is network-based, and the attack complexity is rated as low, meaning that an attacker does not require advanced skills or access to successfully exploit this vulnerability.

Privileges required for this attack are low, as users simply need to submit a request to the endpoint without any special permissions. User interaction is not required, further increasing the risk of exploitation. The potential impacts on confidentiality, integrity, and availability are all rated as low.

Risk & Impact Analysis

The risk associated with this vulnerability is primarily due to its potential for unauthorized data access, particularly for applications handling sensitive information. The blast radius could extend to all systems utilizing this API, making it crucial for organizations to assess their exposure.

Organizations should assess the urgency based on the vulnerability's CVSS score of 2.1, indicating a low severity but still warranting attention. Given the public disclosure of the exploit, it is advisable to monitor for potential exploitation attempts.
