CVE-2025-57956 is a medium-severity Stored Cross-Site Scripting (XSS) vulnerability identified in the WooMS product developed by wpcraft. This vulnerability arises from improper neutralization of input during web page generation, classified under CWE-79. Specifically, the flaw allows an attacker to inject malicious scripts that are stored persistently within the application and later executed in the context of users viewing the affected pages. The vulnerability affects WooMS versions up to 9.12, with no specific lower bound version identified. The CVSS 3.1 base score is 5.9, reflecting a medium severity level. The vector string (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L) indicates that the attack can be performed remotely over the network with low attack complexity, but requires high privileges and user interaction. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes limited confidentiality, integrity, and availability losses. No known exploits are currently reported in the wild, and no patches or mitigations have been linked yet. Stored XSS vulnerabilities can be leveraged by attackers to execute arbitrary JavaScript in the victim’s browser, potentially leading to session hijacking, privilege escalation, or distribution of malware. Given that WooMS is a web-based management system, exploitation could impact administrative users and potentially compromise the integrity of the managed systems or data.

For European organizations using WooMS, this vulnerability poses a risk primarily to administrative and privileged users who interact with the system’s web interface. Successful exploitation could lead to unauthorized actions performed on behalf of these users, data leakage, or manipulation of system settings. This could disrupt business operations, lead to data breaches involving personal or sensitive information protected under GDPR, and damage organizational reputation. The medium severity and requirement for high privileges limit the attack surface but do not eliminate risk, especially in environments where privileged credentials are shared or insufficiently protected. Additionally, the scope change indicates that the impact could extend beyond the immediate component, potentially affecting other integrated systems or services. Organizations in sectors with high regulatory scrutiny or critical infrastructure management may face increased operational and compliance risks if this vulnerability is exploited.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Monitor wpcraft’s official channels for security patches or updates addressing CVE-2025-57956 and apply them promptly once available. 2) Restrict access to WooMS administrative interfaces to trusted networks and users, employing network segmentation and VPNs where feasible. 3) Enforce strict privilege management policies to minimize the number of users with high-level permissions and implement multi-factor authentication to reduce the risk of credential compromise. 4) Implement web application firewalls (WAFs) with custom rules to detect and block suspicious input patterns indicative of XSS attacks targeting WooMS. 5) Conduct regular security assessments and code reviews focusing on input validation and output encoding practices within WooMS deployments. 6) Educate users, especially administrators, about the risks of clicking on suspicious links or interacting with untrusted content that could trigger stored XSS payloads. 7) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing WooMS interfaces. These targeted measures go beyond generic advice by focusing on access control, monitoring, and layered defenses specific to the nature of the vulnerability and the product affected.
