CVE-2026-108052 in ALO Suite
Summary
by MITRE • 11/03/2026
A stored Cross-Site Scripting (XSS) vulnerability in Alosuite that affects the delivery note functionality. Insufficient sanitization and encoding of the specified fields allow JavaScript to be stored, which executes in other users’ browsers when they view the affected records. Exploitation requires authenticated access to the affected functionality. The code can alter the displayed content and perform actions within the context of the victim’s session. The list of features, parameters, and endpoints is as follows:
CVE-2026-108052: Codigo in ‘/CategoriasFicheros/Edit/{id}’;

The vulnerability identified under CVE-2026-108052 represents a critical stored Cross-Site Scripting flaw within the Alosuite application, specifically targeting the delivery note functionality and associated file category management interfaces. This security defect arises from insufficient sanitization and encoding of user-supplied input fields, particularly the Codigo parameter located at the endpoint /CategoriasFicheros/Edit/{id}. When an authenticated attacker submits malicious JavaScript code through this field, the application fails to properly validate or escape the data before storing it in the backend database. Consequently, when any other authorized user subsequently views records associated with these categories, the browser interprets and executes the embedded script within their session context. This mechanism distinguishes stored XSS from reflected variants, as the payload persists on the server side rather than being transmitted solely via URL parameters or HTTP requests during a single interaction.
From an operational perspective, this vulnerability poses significant risks to data integrity and user security because exploitation requires authenticated access but does not require specific administrative privileges if standard users can edit file categories. Once executed, the malicious script operates with the same permissions as the victim’s active session. This allows attackers to perform actions such as stealing sensitive cookies or session tokens, which could lead to account takeover attacks. Furthermore, the attacker can alter the displayed content of the application interface, potentially creating phishing pages that mimic legitimate Alosuite screens to harvest credentials from unsuspecting users. The ability to manipulate DOM elements also enables keylogging capabilities within the context of the vulnerable page, exposing confidential business data entered by employees during their normal workflow activities related to delivery notes and file management.
This vulnerability aligns with CWE-79, which classifies improper neutralization of input during web page generation as a Cross-Site Scripting weakness. The attack vector corresponds to ATT&CK technique T1059.007, specifically JavaScript execution within browser environments, often utilized in conjunction with credential harvesting techniques like T1539 or session hijacking via cookie theft under T1539. Because the payload is stored server-side, it affects multiple victims over an extended period until the malicious data is manually removed from the database, making remediation urgent and comprehensive.
Mitigation strategies must focus on implementing robust input validation and output encoding mechanisms at both the application layer and the presentation layer. Developers should enforce strict allow-listing for all fields accepting user input to ensure only expected character sets are processed. Additionally, context-aware output encoding must be applied when rendering data in HTML contexts to prevent browser interpretation of script tags or event handlers. Implementing a Content Security Policy header can further mitigate impact by restricting the sources from which scripts can load and execute. Regular security audits and static code analysis focused on input handling routines for endpoints like /CategoriasFicheros/Edit/{id} are essential to identify similar flaws across other modules within the Alosuite ecosystem before they can be exploited in production environments.
