CVE-2025-5352
CWE-79Published: August 23, 2025· Updated: Jun 17, 2026
Official Description
A critical stored Cross-Site Scripting (XSS) vulnerability exists in the Analytics component of lunary-ai/lunary versions up to 1.9.23, where the NEXT_PUBLIC_CUSTOM_SCRIPT environment variable is directly injected into the DOM using dangerouslySetInnerHTML without any sanitization or validation. This allows arbitrary JavaScript execution in all users' browsers if an attacker can control the environment variable during deployment or through server compromise. The vulnerability can lead to complete account takeover, data exfiltration, malware distribution, and persistent attacks affecting all users until the environment variable is cleaned. The issue is fixed in version 1.9.25.
Technical Analysis
CVE-2025-5352 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.6.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
