CVE-2025-63743 is a Cross-Site Scripting vulnerability in the Snipe-IT web-based asset management system versions 8.3.0 to 8.3.1. This vulnerability allows an authenticated attacker, with the lowest privileges sufficient to log in, to inject arbitrary JavaScript code through the "Name" and "Surname" fields. The injected JavaScript code executes whenever the "Activity Report" or modified profile is accessed by any user with sufficient permissions.
The vulnerability's exploitation is contingent upon the profile's "Display Name" not being set. The issue was addressed in version 8.3.2, making it imperative for organizations to prioritize patching to mitigate the potential risks.
The CVSS score for this vulnerability is 5.4, categorized as medium severity. The attack vector is network-based with low complexity and requires low privileges. Given its nature, the risk to organizations includes unauthorized execution of JavaScript code, which can lead to further vulnerabilities or data exposure.
Organizations should address this vulnerability promptly by upgrading to version 8.3.2 of Snipe-IT to prevent potential exploitation.
Vulnerability Details
The official description of CVE-2025-63743 states that it is a Cross-Site Scripting vulnerability in Snipe-IT versions 8.3.0 to 8.3.1. The vulnerability allows authenticated attackers to execute arbitrary JavaScript code via "Name" and "Surname" fields. The JavaScript executes when viewing the "Activity Report" or modified profile by any user with adequate permissions.
This vulnerability is classified under CWE-79, and its CVSS score of 5.4 indicates a medium severity level. The attack vector is classified as network-based, with low complexity and low privileges required for exploitation. The vulnerability was published on April 13, 2026.
Technical Analysis
The root cause of the vulnerability lies in the inadequate sanitization of user input fields "Name" and "Surname," allowing for the injection of malicious JavaScript code. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely.
The attack complexity is low, as it requires only low privileges to log in. Importantly, no user interaction is required for the attack to succeed, which elevates the risk. The impacts on confidentiality and integrity are rated as low, while there is no impact on availability.
Risk & Impact Analysis
Risk to organizations includes the potential exposure of sensitive information through unauthorized JavaScript execution, which can compromise user sessions and lead to further attacks if not addressed swiftly. The potential blast radius could include all users who interact with the affected profiles.
Given the CVSS score of 5.4, organizations should address this vulnerability in their priority patch cycle. This vulnerability's inclusion in the CVE database highlights its relevance, and organizations should be aware of its implications for their security posture.
