CVE-2026-108058 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-2026-108058: Nombre in ‘/PlantillasMail/Edit’;

The vulnerability identified under CVE-2026-108058 represents a critical security flaw within the Alosuite enterprise resource planning software, specifically targeting the delivery note management subsystem. This issue is classified as a Stored Cross-Site Scripting (XSS) vulnerability, which poses a significant risk to organizational data integrity and user safety due to its persistent nature. Unlike reflected XSS attacks that require tricking users into clicking malicious links, stored XSS vulnerabilities involve injecting malicious scripts into the application's database or storage mechanisms. In this specific instance, the flaw resides in the handling of input fields within the mail template editing functionality, particularly affecting the Nombre field accessed via the /PlantillasMail/Edit endpoint. The root cause is a failure to properly sanitize and encode user-supplied data before it is stored by the server and subsequently rendered back to other users without adequate validation.
From a technical perspective, the vulnerability arises because the application accepts input for the delivery note or mail template name field but fails to apply rigorous output encoding when displaying this information in subsequent requests. When an authenticated attacker submits specially crafted JavaScript code as part of the Nombre parameter during the editing process, the server stores this payload without modification. Later, when any other authorized user accesses the affected records or views the list of templates, their browser retrieves and executes the malicious script within the context of the victim's active session. This execution environment grants the attacker full access to all functionalities available to that specific user, including the ability to read sensitive data, modify settings, or perform actions on behalf of the victim without their knowledge or consent.
The operational impact of this vulnerability is severe due to its reliance on authenticated access and its persistence within the application's core workflow. Because exploitation requires valid credentials, it typically targets internal users who have legitimate access to delivery note management features. Once exploited, an attacker can steal session cookies, hijack user sessions, or redirect victims to phishing sites designed to harvest additional credentials. Furthermore, since the payload is stored in the database, every subsequent view of the affected record triggers the attack, potentially compromising a large number of users over time if left unpatched. This persistence makes remediation urgent and highlights the critical need for immediate intervention once the vulnerability is confirmed.
In terms of industry standard classifications, this flaw aligns with CWE-79, which describes Improper Neutralization of Input During Web Page Generation commonly known as Cross-site Scripting. The attack vector corresponds to ATT&CK technique T1059.007, specifically JavaScript execution via web browsers, and falls under the broader category of Client-Side Injection attacks found in MITRE's framework for cyber threat intelligence. These mappings underscore that the issue is not merely a coding error but a fundamental breach of input validation principles expected in secure software development lifecycles.
To mitigate this vulnerability, immediate action must be taken to implement robust output encoding on all user-controllable data before it is rendered by the browser. Developers should ensure that special characters such as ampersands, less-than signs, greater-than signs, and quotes are encoded appropriately based on the context in which they appear within HTML structures. Additionally, implementing a Content Security Policy (CSP) can provide an additional layer of defense by restricting the sources from which scripts can be loaded or executed, thereby neutralizing many XSS payloads even if they manage to bypass input filters. Regular security audits and static code analysis tools should also be employed to detect similar sanitization failures across other endpoints within the Alosuite platform before further exploitation occurs.
