CVE-2025-8974 is a medium severity vulnerability affecting linlinjava's litemall product versions up to 1.8.0. The vulnerability resides in the JSON Web Token (JWT) handling component, specifically within the JwtHelper.java file located at litemall-wx-api/src/main/java/org/linlinjava/litemall/wx/util/. The issue arises from the manipulation of the SECRET argument via the X-Litemall-Token input, which leads to the use of hard-coded credentials. This flaw allows an attacker to potentially bypass authentication or gain unauthorized access by exploiting the predictable or static secret used in JWT token generation or validation. The attack vector is remote network-based, requiring no privileges or user interaction, but the complexity of exploitation is considered high, indicating that a successful attack would require significant effort or expertise. Although the exploit has been publicly disclosed, there are no known exploits actively used in the wild at this time. The CVSS 4.0 base score is 6.3, reflecting a medium severity rating, with the main impact being limited integrity loss due to potential token forgery or manipulation. Confidentiality and availability impacts are not significant. The vulnerability does not require authentication or user interaction, but the high attack complexity reduces the likelihood of widespread exploitation. This vulnerability highlights the risks of embedding hard-coded secrets in security-critical components like JWT handlers, which can undermine the entire authentication mechanism if compromised.

For European organizations using linlinjava litemall versions up to 1.8.0, this vulnerability could lead to unauthorized access to protected resources or user accounts by allowing attackers to forge or manipulate JWT tokens. This could result in integrity breaches, such as unauthorized transactions, data modification, or privilege escalation within the affected application. While confidentiality and availability impacts are minimal, the integrity compromise can have significant operational and reputational consequences, especially for e-commerce platforms or services relying on litemall for user authentication and session management. Given the medium severity and high exploitation complexity, the immediate risk is moderate, but organizations should not underestimate the potential for targeted attacks, particularly in sectors handling sensitive customer data or financial transactions. Additionally, the public disclosure of the vulnerability increases the risk of future exploitation attempts, necessitating timely remediation to prevent abuse.

European organizations should prioritize upgrading linlinjava litemall to a version where this vulnerability is patched or the hard-coded credentials issue is resolved. If an immediate upgrade is not feasible, organizations should implement compensating controls such as: 1) Reviewing and rotating any secrets or tokens related to JWT handling to ensure they are unique and not hard-coded. 2) Implementing additional authentication layers or multi-factor authentication to reduce reliance on JWT tokens alone. 3) Monitoring application logs for suspicious JWT token usage or anomalies in authentication flows. 4) Restricting network access to the litemall API endpoints to trusted IP ranges or VPNs to reduce exposure. 5) Conducting code audits to identify and remove any other instances of hard-coded secrets. 6) Applying runtime application self-protection (RASP) or web application firewall (WAF) rules to detect and block malformed or suspicious JWT tokens. These measures will help mitigate the risk until a secure patch is applied.
